Engineering, Building, and Architecture - Overview
Not many museums collect houses. The National Museum of American History has four, as well as two outbuildings, 11 rooms, an elevator, many building components, and some architectural elements from the White House. Drafting manuals are supplemented by many prints of buildings and other architectural subjects. The breadth of the museum's collections adds some surprising objects to these holdings, such as fans, purses, handkerchiefs, T-shirts, and other objects bearing images of buildings.
The engineering artifacts document the history of civil and mechanical engineering in the United States. So far, the Museum has declined to collect dams, skyscrapers, and bridges, but these and other important engineering achievements are preserved through blueprints, drawings, models, photographs, sketches, paintings, technical reports, and field notes.

Post Instruction Manual for Versalog Slide Rule
- Description
- This is a later printing of 1978.0800.02. Its citation information is: E. I. Fiesenheiser, Versalog Slide Rule Instruction Manual, with R. A. Budenholzer and B. A. Fisher (Chicago: Frederick Post Company, 1963). The text appears not to have been revised since these three Illinois Institute of Technology engineering professors helped invent the Versalog slide rule and wrote instructions for using it in 1951. Marks inside the front cover indicate this copy was offered for sale in January 1969 for $1.00.

Hemmi Duplex Slide Rule Retailed by Post (Versalog 1460)
- Description
- The Frederick Post Company, a 20th-century manufacturer and retailer of scientific instruments based in Chicago, did not make its own slide rules. From 1932, its exclusive supplier of linear slide rules was Hemmi, a Japanese firm. Hemmi was known for using a large-diameter variety of bamboo grown in Kagoshima Prefecture on the island of Kyushu. Company founder Jiro Hemmi (1878–1953) patented this innovation in several nations, including the United States in 1920.
- While Post usually sold standard Hemmi models, around 1951 Hemmi created two ten-inch slide rules solely for Post, which sold in the United States as the model 1450 Versatrig and model 1460 Versalog. The Versalog was especially popular, selling several hundred thousand copies.
- This example is bamboo, coated on all sides (except the ends) with white celluloid. The rule is held together with metal posts, one of which is engraved on the front: Wm. Krutz. The glass indicator has a metal frame with plastic sides. One side is marked: HEMMI JAPAN. The other side bears a Post logo in red, which has largely been rubbed away. The red Post logo and the serial number 015836 appear on the right front of the slide. The serial number indicates the rule was manufactured in 1959. This is confirmed by the date code JI on the bottom edge of the rule, which corresponds to a manufacturing date of September 1959.
- The top edge of the rule is marked: CAT. NO. 1460; VERSALOG; FREDERICK POST CO.; HEMMI BAMBOO – JAPAN. The front of the base has LL0, LL/0, K, DF, D, R1, R2, AND L scales. The front of the slide bears CF, CIF, CI, and C scales. The LL/0, CIF, and CI scales are numbered in red. The back of the base has LL/1, LL/2, LL/3, D, LL3, LL2, AND LL1 scales. The back of the slide has T, Sec T and ST, Cos and S, and C scales. The LL/1, LL/2, LL/3, T, and Sec T scales are numbered in red. All the other scales are navy.
- The rule fits into a black Fabrikoid case with a leather flap (stamped POST). The case could be hung from the user's belt, and it is labeled: W. K. KRUTZ. The case is stored in a red, white, and black cardboard box, along with a guarantee from Post and a ruler-sized white plastic set of conversion tables, copyrighted in 1950 by the Eugene Dietzgen Co., another prominent slide rule manufacturer. The rule also arrived with an instruction booklet, 1978.0800.02.

Hemmi Simplex Slide Rule Retailed by Post (1447)
- Description
- This ten-inch one-sided bamboo rule is coated with white celluloid only on the front. There is no indicator. The base has A, D, and K scales. The slide has B, CI, and C scales on one side and S, L, and T scales on the other side. The CI scale is numbered in red. The base is held together with a sheet of metal and with clear celluloid that has red hairlines at each end. The back of this metal and celluloid backing contains a chart on white plastic. The chart provides various relationships or conversions between the C and D scales as well as fundamental trigonometric relationships.
- The instrument is marked in red at the top center of the base: FREDERICK POST CO. 1447. It is marked in black at the top right: HEMMI JAPAN. The Post logo (in red) appears at the right side of the slide. The back is stamped with the date code TD, indicating the rule was manufactured in April 1969. The style of the Post logo is consistent with this date.
- The Frederick Post Company of Chicago imported slide rules made by the Japanese firm of Hemmi from about 1932 to the 1970s, with a brief interruption during World War II. Post sold Model 1447 from about 1949 to about 1971.
- Chemist Albert S. Matlack donated this slide rule. He recalled that it was mainly used by his laboratory technician at the Hercules Research Center in Wilmington, Del.

Hemmi Simplex Pocket Slide Rule Retailed by Post (1441)
- Description
- This small (five-inch) one-sided slide rule is bamboo covered with white celluloid, with a clear celluloid and metal backing. A magnifying glass indicator has a metal frame. There are A and D scales on the base. The slide has B, CI, and C scales on one side and S, L, and T scales on the other side. The upper edge of the base has a four-inch ruler divided to thirty-seconds of an inch.
- The back of the base is marked: THE FREDERICK POST CO. NO. 1441 (/) SUN (between two drawings of the sun) HEMMI JAPAN CF. A brown leather case is stamped on the flap: POST. Inside the case is stamped: MADE IN JAPAN and handwritten: R. FREEZE.
- The instrument was made by the Hemmi Slide Rule Company of Tokyo, Japan, and sold by the Frederick Post Company of Chicago, Ill. In the 1930s and 1940s, Post sold this model for $2.70. The code CF on the slide rule indicates that this example was manufactured by Hemmi in June 1952. The donor, Richard Freeze, purchased it in Philadelphia around 1956–57, when he was a student at Drexel Institute of Technology (later Drexel University). He used it during classes in physics, mathematics, and industrial engineering. Later, he used it while working at a specialty chemical firm doing industrial engineering projects.
- Compare to 1995.0087.01.

Post Instruction Manual for Versalog Slide Rule
- Description
- In 1950 and 1951, three Illinois Institute of Technology engineering professors participated in the development of the Versalog slide rule, manufactured by Hemmi of Tokyo, Japan, for the Frederick Post Company of Chicago. E. I. Fiesenheiser, R. A. Budenholzer, and B. A. Fischer subsequently prepared this 115-page hardcover volume explaining the slide rule's capabilities. They covered the care of the instrument, its twenty-three scales, multiplication and division, squares and cubes, exponentials and logarithms, and trigonometric operations. Each professor also contributed a chapter on applications in his specialty: civil, mechanical, or electrical engineering.
- This copy is stamped inside the front cover and on the edges: WILLIAM KRUTZ ESQ. See 1978.0800.01.
