Computers & Business Machines

Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.
The museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. Computers range from the pioneering ENIAC to microcomputers like the Altair and the Apple I. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

Hermes Baby Rocket Typewriter
- Description
- This portable Hermes Baby Rocket brand typewriter was manufactured by Hermes-Presica, a division of Paillard Incorporated, around 1966. Paillard Incorporated was based in Switzerland, but the factory that produced this typewriter was located in Sackingen, Germany. Hermes manufactured a variety of typewriter models under both the “Baby” and “Rocket” brand name, and the design was so popular that it was licensed to several other manufacturers.

IBM Electric Model 01 Typewriter
- Description
- This electric typewriter was manufactured by the International Business Machines (IBM) Corporation around 1935. IBM purchased Electromatic Typewriters, Inc. in 1933, taking over its Rochester, New York factory. After a variety of improvements IBM issued the IBM Electric Typewriter Model 01 in 1935. The innovation of electric typewriters was that each type bar hit the paper with the same force, and that force was more powerful than manual typewriters. This was especially useful in business situations as multiple carbon copies could be produced. IBM continued producing typewriters, including the very popular Selectric model, throughout the 20th century until 1990.

Graphophone
- Description
- This is a business dictation machine that uses wax cylinders to record and play back sound. The basic design for the machine emerged from research at the Volta Laboratory, Washington, D.C., the sound research facility established by Alexander Graham Bell with his associates Chichester Bell and Charles Sumner Tainter.
- Tainter refined the design, patented several versions of it, and oversaw the manufacturing of the first six experimental graphophones at Bergmann & Co in New York in 1885. He also supervised the making of commercial models in a sewing machine factory in Bridgeport, Conn., beginning in 1887. In these early commercial machines, the dictation apparatus sits atop a sewing machine table and employs a treadle to rotate the mandrel holding the cylinder recording.
- On this machine from 1888, the treadle is marked "American Graphophone Company"; the governor is marked "Patented July 20th 1886." The recorder-reproducer is marked: "The Phonograph-Graphophone m'f'd by the American Graphophone Company for Jesse H. Lippincott, Sole Licensee/ Type C No. 03042" and numerous patent dates.

Columbia No. 2 Typewriter
- Description
- This Columbia No. 2 typewriter was manufactured by the Columbia Typewriter Company of New York after 1886. The typewriter was invented by Charles Spiro, and covered by patent number 322,989 and 335,392. The Columbia typewriter was an index typewriter, meaning that the letters were selected with a pointer, manipulated by the index finger, and imprinted by pressing another key. The absence of the keyboard made the typewriter simpler to operate, but sacrificed speed and efficiency. The machine also had variable spacing, allowing each letter to take up a varying amount of space, for instance, an “I” take up less space than an “M.”

Hammond Multiplex Typewriter
- Description
- This Hammond Folding Multiplex typewriter was manufactured by the Hammond Typewriter Company of New York beginning in 1923. The typewriter uses Hammond’s patented type-shuttle and hammer typing mechanism where the printing is done by a hammer in the back of the machine striking a type-carrying shuttle in the front of the machine, with the paper and ink ribbon in between to receive the impression. This Hammond Folding Multiplex contains two additional Hammond innovations. It is called a Multiplex because the typewriter contains two type shuttles that can easily be rotated into use, allowing the typing of two complete alphabets in different typesets on each machine. This typewriter’s keyboard could also fold up to allow a cover to be attached to the base, allowing the typewriter to be carried. The keyboard is in a three row QWERTY array.
- James Bartlett Hammond filed patents for his type-shuttle and hammer typing mechanism present in Hammond typewriters in 1879, receiving patent number 224088 on February 3rd, 1880 and patent number 232402 September 21st, 1880. The Hammond Typewriter Company was founded in 1880, and produced its first machine by 1884, winning a gold medal at the New Orleans Centennial Exposition that same year. The Hammond Typewriter touted its superior strength and durability due to its unique type-shuttle and hammer typing mechanism. The replaceable type-shuttle also contributed to the Hammond’s popularity with the ability to print in a variety of typesets in various sizes, including math formulae, special symbols, and foreign characters with an easy replacement of the type shuttle, or an even simpler rotation of a wheel in the Hammond Multiplex.

Underwood Model 5
- Description
- The Underwood Model 5, introduced in 1899, is the result of almost thirty years of innovation and improvements in typewriter manufacture. It became the ubiquitous office machine for another thirty years, and its sales led Underwood to dominate the market. The Model 5 became the modern standard of how a typewriter worked and what it looked like.
- The first successful commercial typewriter, developed by Christopher Scholes and Carlos Glidden, was brought to the public in 1874 by the Remington Company. Two elements from that first machine remained dominant in the design of eventual typewriters: the QWERTY keyboard, a pattern of letters on the keyboard, and the telegraph type key movement. At first sales were slow, but the typewriter industry grew as businesses expanded along with their need to retain records, and process paperwork at fast speeds. More and more people, mostly women, learned the new skill of typing, creating a new class of clerical worker, according to historian JoAnne Yates.
- There were a handful of typewriter manufacturers by the end of the 1880s such as Remington, a leader in the industry, L.C. Smith & Brothers, Caligraph, Hammond, and a number of smaller firms. As the number of manufacturers grew, so too did the improvements, including the addition of a shift key to activate upper and lower case letters, the size and weight had been reduced but until 1895, but typists could not see what they had typed until the typed page advanced forward.
- In the early 1890s, Franz X Wagner, a German immigrant, engineered the first reliable "visible" typewriter that allowed the typist to see the text as they typed. Wagner had already designed several earlier typing machines. John T. Underwood, producer of office supplies such as carbon paper and ribbons, purchased Wagner's design and manufactured it as the Underwood Model 1 in 1895. Unlike earlier machines, which had an up strike type bar from underneath the paper, the new design in
- After six years and two other models that improved touch, and tab function and provided quieter operation, Underwood came out with the Model 5 in 1900. Compared to earlier machines of the 1870s, this machine is plain. The machine in the collection was produced in 1910. It has a black frame with gold lettering and stripping.
