Records of Weiskopf & Pickworth Consulting Engineers |
| Dates: | 1901-1971, 1998 |
| Abstract: | Weiskopf & Pickworth Consulting Engineers were a successful
partnership of Samuel Weiskopf and John Pickworth founded in 1920. Among many
accomplishments, the firm was responsible for the first concrete dome in the United States
constructed for the Hayden Planetarium in New York's American Museum of Natural History in
1932. In 1933, Pickworth and Walter Weiskopf were granted a patent for the WP girder (also
known as T-flange girder) which reduced the depth of a girder by up to one foot. This collection
documents the history of this firm which includes: photographs, patents, drawings, blueprints,
press releases, manuscripts, correspondence, pamphlets, and news clippings. |

Samuel C. Weiskopf founded his firm in New York
in 1898, leaving his post as engineer at Carnegie Steel in order to advance the state of steel
design by working with both client and architect. He worked in close collaboration with
distinguished architects including Francis H. Kimball and Trowbridge & Livingston on projects
such as The Trinity Building, the Bankers Trust Company Building, and the Knickerbocker
Hotel. In 1916 John W. Pickworth was hired by Weiskopf to be assistant engineer. Pickworth
had previously worked with Post & McCord steel contractors as a draftsman. In 1920 Pickworth
became Weiskopf's partner, and the firm name was changed to Weiskopf & Pickworth
Consulting Engineers. Although the firm's practice remained active in New York City, Weiskopf
& Pickworth was commissioned by Mitsui Bank in Japan, as well as by cities and towns across
the United States. From 1913 to 1929, the firm engineered 55 banks in locations from Bangor,
Maine to Oshkosh, Wisconsin. In 1930 Samuel Weiskopf retired to be replaced by his
27-year-old son, Walter.
During the Great Depression the firm developed two
significant innovations. In 1932 the first concrete dome in the United States was constructed for
the Hayden Planetarium in New York's American Museum of Natural History. Weiskopf &
Pickworth conducted extensive studies on reinforced concrete to engineer the thin concrete shell
dome. In 1933 John Pickworth and Walter Weiskopf were granted a patent for the WP girder
(also known as T-flange girder). The invention of the WP girder reduced the depth of a girder by
up to one foot, and it was used in projects requiring extremely heavy girders with long spans.
In 1946, two years after his return from his leave to serve as head engineer for the
New York District of the Army of Corps of Engineers, Walter Weiskopf hired Anthony Nassetta
whom he worked with in the Army Corps. In 1948, Anthony Grasso and Morton Eligator joined
the firm, followed by Emanuel Pisetzner in 1953. These four men took on increasing
responsibility during the postwar era, and shaped the firm for the next 40 years. In 1952,
restrictions placed on building materials due to the Korean War prompted the firm's invention of
the first long span precast concrete girders replacing the need for long span steel girders. The
1950s also saw the growth in collaboration between the firm and Gordon Bunshaft of Skidmore,
Owings & Merrill. Embracing modernism, they built the Lever House, a glass and steel tower
that is credited with bringing International Style architecture to the United States. The publicity
of the Lever House generated a public relations boost, and the two firms continued their
collaboration on many other projects, including One Chase Manhattan Plaza, the Union Carbide
Headquarters and the Equitable Life Assurance Society Home Office Building. In 1960, Anthony
Nassetta, Anthony Grasso, Morton Eligator and Emanuel Pisetzner were made Partners.
The 1960s saw the growing working relationship between Weiskopf & Pickworth and I.M.
Pei & Associates and the shift in favor by architects from glass and steel structures to concrete
structures. The two firms collaborated on the American Life Insurance Company Building in
Wilmington, Delaware; L'Enfant Plaza in Washington, DC and the Christian Science Church
Center in Boston, Massachusetts. Their relationship will continue into the next several decades
with the building of the Canadian Imperial Bank of Commerce Headquarters (1973), the East
Wing of the National Gallery of Art in Washington, DC (1978), and Raffles City (1979-1986).
Between 1985 and 1990 Nassetta, Grasso and Eligator retired. Louis Occhicone and
Sing Chu were made Senior Associate Partners in 1985, and full Partners in 1990. Pisetzner, the
last of the four partners who represented the firm for forty years, retired in 1993. In 1992 the firm
entered into partnership with Oscar Faber, an international, multi-disciplinary engineering firm
based in the United Kingdom. The merger proved difficult, however, and the partnership
dissolved in 1995. Under the new leadership of Occhicone and Chu, close collaboration with the
Pei firm (now Pei Cobb Freed & Partners) continued and they engineered The United States
Holocaust Memorial Museum (1987-1993) and the Ronald Reagan Building and International
Trade Center (1990-1997).

"Bankers Trust Co., Wall & Nassau St[reet]s" and "Post & McCord, Steel Builders, New York" printed in the lower corners of the photograph and "Underhill, 289 Broadway, New York" embossed in the lower corners of the photograph. Photograph captions (in square ([])* brackets) by structural engineer Derek Trelstad. |
| Box | Folder | Title | Date |
| 5 | 1 | B16935, made 1910 Oct. 31, 7.5 x 9.5 in. / 19 x 24 cm. | | 1910 |
| | | [Temporary bracing at Wall Street. The stiff-legged derricks at the sidewalk and along the west lot line were probably used to remove spoil from the excavation.] | |
| 5 | 2 | B16936, made 1910 Oct. 31, 7.5 x 9.5 in. / 19 x 24 cm. | | 1910 |
| | | [The gentleman in the jacket and bow tie at the bottom of the photograph, probably a site superintendent for steel erectors Post & McCord, looks on as the mast of a stiff legged derrick is placed. The lower end of the mast will be placed on the cast-iron plate bolted to the timbers to the left in the photo. The leg of the derrick rests on the temporary shoring and provides a temporary platform for the superintendent to observe the work.] | |
| 5 | 3 | B16987, made 1910 Nov. 15, 7.5 x 9.5 in. / 19 x 24 cm. | | 1910 |
| | | [The first steel columns appear among the mazes of temporary timber shoring. The steel fabricator's main stiff-legged derrick has been erected on the new steel columns. Smaller derricks are visible below; they were probably used to remove materials such as the temporary shoring from the excavation.] | |
| 5 | 4 | B17044, made 1910 Nov. 30, 7.5 x 9.5 in. / 19 x 24 cm. | | 1910 |
| | | [The first tier of steel columns nears completion.] | |
| 5 | 5 | B17083, made 1910 Dec. 16, 9.5 x 7.5 in. / 24 x 19 cm. | | 1910 |
| | | [The steel frame has been raised to the ground floor level and planked to provide a temporary work platform. The main erection derrick has been placed so that steel members arriving by truck or cart can be picked from both Wall and Nassau Streets. The platform over Nassau Street has been removed. Materials are stored in the street and over what appears to be a sidewalk vault east of the new building.] | |
| 5 | 6 | B17100, made 1910 Dec. 27, 9.5 x 7.5 in. / 24 x 19 cm. | | 1910 |
| | | [Bystanders watch as a column is set along the Wall Street elevation. The derrick holds the third column from the east while mechanics align the pre-drilled holes for the rivets. The two man crew just behind the hoarding at the left edge of the photo may be the forgeman and his helper preparing rivets. It is also likely that the column is being placed and held in place temporarily with bolts or pins and that the two man crew is excavating for the sidewalk vault under Wall Street.] | |
| 5 | 7 | B17115, made 1911 Jan. 6, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [The second tier of steel columns have been placed, completing the second floor, just below the two-story main banking room. A small derrick has been erected to facilitate movement of materials, including the boom of the stiff-legged derrick. The steel has reached a level that requires resetting the main erection derrick.] | |
| 5 | 8 | B17139, made 1911 Jan. 16, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [A week after the previous photo (B17139) the derrick has been reset and the third tier of columns has been erected. Temporary protective staging is being constructed along Nassau and Wall Streets to protect passersby and to provide a temporary work platform. Steel to be placed has been piled on the planked second floor deck and over the Wall Street sidewalk vault. The built-up sections at street level (Wall Street elevation) will be secured to the shear tabs-steel plates secured to the sides of the columns-that are visible on most columns.] | |
| 5 | 9 | B17171, made 1911 Jan. 28, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [The floor above the Main Banking Room is supported at the perimeter of the building on deep girders, which appear to bear on secondary columns just inside the main columns (compare this photo with the image captured on January 16 [B17139]). The steel arrived from the fabricator with a coat of red lead or iron oxide paint. Once it is set in place it is coated with a waterproofing paint-likely an asphalt-based compound-that provides a measure of protection against corrosion after the masonry has been set.] | |
| 5 | 10 | B17180, made 1911 Feb. 1, 7.5 x 9.5 in. / 19 x 24 cm. | | 1911 |
| | | [At the right side of the photo a mechanic kneels over a bucket. Loose cold rivets lie nearby, suggesting that this photo was taken early in the morning before the forgeman had set up his fire. It is also possible that the forgeman may have been on a lower level and the mechanic visible here is the riveter's assistant; a fuzzy second figure-the riveter-appears to be clinging to the far side of the column behind the kneeling mechanic. In the foreground, a girder is being placed. The fuzzy figure just to the left of the column (left center of photo) is an ironworker guiding the girder in place. The wind bracing system for the building is visible in the heavy diagonal members, as are the fabricators markings on the gusset plate just to the right of the derrick.] | |
| 5 | 11 | B17214, made 1911 Feb. 11, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [Steel erection continues.] | |
| 5 | 12 | B17230, made 1911 Feb. 21, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [Stone packed in wood crates has arrived on site. Unopened crates have been placed on the protective staging near where they will be installed on the building. Stone, like terra cotta used on less monumental structures, was fabricated to fit in a specific location on the fa硤e. The dimensions of each piece were scaled from the architect's drawings by the stone fabricator during earlier phases of construction, long before any of the steel was placed. Using both the architect's drawings and actual field measurements, the fabricator developed drawings showing the full building, keyed to smaller drawings depicting each stone and its dimensions. These drawings were reviewed by the architect and, when necessary, the engineer. Corrections to the design of the stone work and the connection detail between the stone and the steel frame, as well as the dimensions of each unit were made on paper before a chisel touched stone. The process of reviewing and revising these shop drawings often took many weeks.] | |
| 5 | 13 | B17231, made 1911 Feb. 21, 7.5 x 9.5 in. / 19 x 24 cm. | | 1911 |
| | | [As the steel frame progressed upward, masons followed on the exterior with the stone cladding. At the interior a second crew of carpenters and masons constructed the floor structure. While the floor structure is not visible in any of the photos in this series, there are several clues in this image that suggest the floor system is a flat hollow tile arch. At the upper floor in the photo, pairs of holes are visible just above the middle of the web of each beam. Tie rods will be threaded through these holes-as they have been at the lower floor-prior to the placement terra cotta blocks that comprise the tile arch. The tie rods countered the thrust of the flat arch against the steel floor beams. At the lower floor, hangers secured to the top flange of the beams support timber "centering." The tile blocks of the flat arch-"skews" at the beams, "keystones" at the center, and "inters" between-will be placed on the temporary timber centering. When the keystone or central block has been placed and the mortar allowed to cure the centering and hangers are removed. Suspending the centering from the beams minimized the need to provide extensive temporary shoring bearing on the lower floor-reducing costs and expediting construction.] | |
| 5 | 14 | B17232, made 1911 Feb. 21, 7.5 x 9.5 in. / 19 x 24 cm. | | 1911 |
| | | [See caption for previous photo (B17231).] | |
| 5 | 15 | B17274, made 1911 Mar. 3, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [The stiff legged derricks at the sixth floor level of the steel frame have been placed to allow the masons to lift the heavy stones that make up the exterior cladding.] | |
| 5 | 16 | B17303, made 1911 Mar. 13, 9.5 x 7.5 in. / 24 x 19 cm. | | 1911 |
| | | [The speed with which a steel frame could be erected is graphically revealed when this photo is compared with that taken on March 3, 1911 (B17274). In the course of approximately five working days the steel fabricator has almost completed erection of another tier of two-story columns. The masons, working the same hours, have completed placing the stone on approximately one-half story. While the stone work at the lower levels of this building is rather intricate, progress on a simpler masonry fa硤e would not have been as great as that made by the steel fabricator. In fact, the direct comparison of the speed of masonry and steel construction needs also to account for the work underway at the interior of the structure-placement of floor systems, construction of demising partitions and roughing-in plumbing and other utilities. In a masonry bearing wall building, the floors of the upper stories cannot be placed until the masonry reaches the level of the upper stories-and a sufficient time must be provided to allow the mortar in the masonry to set.] | |

| | | [While the steel frame skyscraper dramatically changed the skylines of cities like New York and Chicago with forms achievable only with the new technology of steel frames, the technology of assembling and filling the frames remained comparatively archaic. Riveting required teams of three to four men-a forgeman, a riveter, and one or two helpers. Rivets were heated in a forge to a red heat. The hot rivet was tossed by the forgeman or his helper to the riveter or his helper and placed in a hole. The helper then placed a dolly on the head of the rivet while the riveter manually hammered a second head on the narrow end of the rivet. By the late 1920s that process had become automated to some extent. The manual hammering of rivets was ultimately replaced after the introduction of pneumatic riveting hammers.] | |

| | | [To the left of the nearly completed steel frame stands the steeple of Trinity Church; and to the right beyond the Hanover National Bank, the domed top of the Singer Building is visible. Both buildings were at one time the tallest in New York City.] | |

| | | [At the main shaft of the tower the masons made more rapid progress than at the lower stories, which had more intricate masonry finishes. In the past nine working days the masons-whose suspended rigs are visible just below the mid-point of the tower shaft-have completed approximately one story every two days.] | |

| | | [Topping out-the ritual of placing a pine bough on the uppermost member of a recently completed structure-is usually an occasion for a photograph and a bit of festivity. The steel frame is has not been completed in this photo, but the ironworkers posed for the photographer hired by the contractor or owner to document construction.] | |

| | | [This crew of mechanics have rigged the upper portion of the steel frame for placement of the next beam. Hard hats and safety harnesses-a regular part of any ironworkers kit today-were virtually unknown at the turn of the twentieth century.] | |
