Life

Lubkin studied mathematics at Cooper Union in New York City, and was president of the Cooper Union Mathematics Club in the 1923-1924 academic year. He received a PhD in applied mathematics from Courant Institute of Mathematical Sciences. [1]

He later went on to work on the design of the ENIAC computer while at the Moore School of Electrical Engineering at the University of Pennsylvania. [2] [3]

Lubkin afterwards joined the US Army's Ballistic Research Laboratory to work with other ENIAC designers on the design of the EDVAC computer's programming system, [4] [5] [6] It has been claimed that the "Operating Manual for the EDVAC", which was authored by Lubkin, was "the bible of the computer industry in the late 1940s and early 1950s". [7]

After that he joined the design team who went on to build the first UNIVAC computer. [8] [9]

In the 1940s, Reeves Instrument Corporation hired Lubkin to lead a project designing their first digital computer. Reeves later decided to build analogue computers instead (which ultimately resulted in the Reeves Electronic Analog Computer series of machines), and Lubkin left the company for a job in the digital computer division of the National Bureau of Standards (the US government organization later renamed the National Institute of Standards and Technology). [8]

The bureau essentially hired Lubkin to replicate his design for the EDVAC, and this would go on to become the bureau's SEAC computer. [10]

Electronic Computer Corporation

Within a few months, Lubkin left the bureau, and started his own company with Murray Pfefferman, who had been part of the SEAC design team, with Lubkin as president. This was the Electronic Computer Corporation. The company was established in Brooklyn, New York, as that is where Lubkin's extended family lived. Even as a fledgling enterprise, the company was able to hire several very experienced engineers who had a pedigree in large corporations like the Eckert–Mauchly Computer Corporation (creator of the ENIAC), as prominent Jewish scientists and engineers were losing their security clearance (and consequently, their defense sector jobs) as a result of the House Un-American Activities Committee, which sometimes equated Jewish heritage with Communist sympathies. Other notable employees included Evelyn Berezin. [11]

The main product of this company was a "low cost" (for the time) digital computer named the ELECOM 100. [8] This was a vacuum tube computer with a drum memory. It was also the first computer in history that operated with magnetic tape data storage, which was a separate peripheral. While smaller than some other room-sized computers, the ELECOM 100 was still not small by modern standards. The machine measured 10 feet wide by 6 feet high by 2 feet deep, not including the desk the operator would need to sit at, plus space for other sundry peripherals. [12] The ELECOM 100 was successfully tested for use at Ballistic Research Laboratory, though there is no evidence BRL ever actually purchased any. There was a unit known to be at the Stevens Institute of Technology in New Jersey, but is unknown who else the ELECOM's early users were, and how many were made. [13] In 1955, it was reported that there were a total of three units in operation. [14]

A subsequent model named the ELECOM 120 was developed. This was essentially the ELECOM 100 (which worked on an octal system) modified for decimal operation, and given expanded memory capacity. [13] In 1955 it was reported that there were five ELECOM 120s in operation; users included Griffiss Air Force Base, Westinghouse Aviation Gas Turbine Division and Shell Development Laboratories (now called Shell Development Emeryville). [14] An ELECOM 50 machine also existed, though this was a purpose-built accounting machine, [12] and an ELECOM 125. [14] [15] [note 1] [16]

The ELECOM computers were reasonably successful in the market. In 1953, the Electronic Computer Corporation was acquired by the Underwood Typewriter Company, though Lubkin would stay on as Technical Director of their Electronic Computer Division. In interviews he spoke of pressure to produce cheaper and cheaper machines, and spoke of belief that the future of computing was in less-expensive, purpose-built machines for industry, and not in general purpose computing. [17]

However the Electronic Computer Corporation suffered as a division within the financially ailing typewriter company. Underwood eventually realized it did not have the financial strength to produce the inventory needed to sell the (individually expensive) ELECOM machines, even those that it was already under contract to produce. There was an outstanding order for ELECOM machines from Standard Oil that the chairman of Underwood had to back out of. [18] In 1957 Underwood would get out of the computer business entirely, closing its computer division, after which Lubkin left. [9]

Later career

Lubkin would go on to work as a designer and consultant for computer projects with New York University, Curtiss-Wright, and Republic Aviation. [1]

In 1962, he founded a company of his own called Digital Electronics Inc., and was named chairman of the board. [1] The company set out to focus on "custom-designed data conversion equipment, educational training devices, and a proprietary line of pulse and digital test equipment." [19] Lubkin would apply for and receive several patents for the company, [20] though he and the company would wind up becoming embroiled in litigation with some of his cofounders. [21]

Personal life

Samuel Lubkin had one son, Yale Jay Lubkin (husband to science journalist Gloria Lubkin from 1953 to 1968), with whom he worked at Digital Electronics Inc. He also had one daughter, Annice. He died in 1972.

SEAC was a first-generation electronic computer, built in 1950 by the U.S. National Bureau of Standards (NBS) and was initially called the National Bureau of Standards Interim Computer, because it was a small-scale computer designed to be built quickly and put into operation while the NBS waited for more powerful computers to be completed. The team that developed SEAC was organized by Samuel N. Alexander. SEAC was demonstrated in April 1950 and was dedicated in June 1950; it is claimed to be the first fully operational stored-program electronic computer in the US.

The Eckert–Mauchly Computer Corporation (EMCC) was founded by J. Presper Eckert and John Mauchly. It was incorporated on December 22, 1947. After building the ENIAC at the University of Pennsylvania, Eckert and Mauchly formed EMCC to build new computer designs for commercial and military applications. The company was initially called the Electronic Control Company, changing its name to Eckert–Mauchly Computer Corporation when it was incorporated. In 1950, the company was sold to Remington Rand, which later merged with Sperry Corporation to become Sperry Rand, and survives today as Unisys.

Honeywell, Inc. v. Sperry Rand Corp., et al., 180 U.S.P.Q. 673, was a landmark U.S. federal court case that in October 1973 invalidated the 1964 patent for the ENIAC, the world's first general-purpose electronic digital computer. The decision held, in part, the following: 1. that the ENIAC inventors had derived the subject matter of the electronic digital computer from the Atanasoff–Berry computer (ABC), prototyped in 1939 by John Atanasoff and Clifford Berry, 2. that Atanasoff should have legal recognition as the inventor of the first electronic digital computer and 3. that the invention of the electronic digital computer ought to be placed in the public domain.

Theory and Techniques for Design of Electronic Digital Computers was a course in the construction of electronic digital computers held at the University of Pennsylvania's Moore School of Electrical Engineering between July 8, 1946, and August 30, 1946, and was the first time any computer topics had ever been taught to an assemblage of people. The course disseminated the ideas developed for the EDVAC and initiated an explosion of computer construction activity in the United States and internationally, especially in the United Kingdom.

An accounting machine, or bookkeeping machine or recording-adder, was generally a calculator and printer combination tailored for a specific commercial activity such as billing, payroll, or ledger. Accounting machines were widespread from the early 1900s to 1980s, but were rendered obsolete by the availability of low-cost computers such as the IBM PC.

The Ballistic Research Laboratory (BRL) was a leading U.S. Army research establishment situated at Aberdeen Proving Ground, Maryland that specialized in ballistics as well as vulnerability and lethality analysis.

In computer science, a digital electronic computer is a computer machine which is both an electronic computer and a digital computer. Examples of digital electronic computers include the IBM PC, the Apple Macintosh, and modern smartphones. When computers that were both digital and electronic appeared, they displaced almost all other kinds of computers, but computation has historically been performed in various non-digital and non-electronic ways: the Lehmer sieve is an example of a digital non-electronic computer, while analog computers are examples of non-digital computers which can be electronic, and mechanical computers are examples of non-electronic computers.
