January 4, 1972 - Hewlett-Packard introduces the HP-35: Hewlett-Packard introduces the HP-35, the first scientific handheld calculator and the final step in ending reliance on slide rules among scientists and students alike. The HP-35 was named for its 35 keys, weighed nine ounces, and sold for $395. One of the tests HP co-founder Dave Packard applied to the device was to throw it across his office and see if it still worked. It did.

January 5, 1962 - The First Reference to Simula in Writing is Made: The first reference to Simula in writing is made. This early object-oriented language was written by Kristen Nygaard and Ole-John Dahl of the Norwegian Computing Center in Oslo. Simula grouped data and instructions into blocks called objects, each representing one facet of a system intended for simulation.

January 6, 1942 - Peter Denning, a Developer of Virtual Memory, is Born: Peter Denning is born. He received a BEE from Manhattan College in 1965 and a PhD from MIT in 1968. He was head of the computer science department at Purdue University (1979-83), co-founder of CSNET and first chair of the CSNET executive committee (1981-1986), and the founding director of the Research Institute for Advanced Computer Science at the NASA Ames Research Center (1983-1990). Since 1991 he has become Professor of Computer Science at George Mason University.

BBC News recently posted the work of Alex Dragulescu - an artist who created "visualisations of computer viruses by looking at their behaviour, including the way they branch out and infect even more machines."

December 14, 1954 - Whirlwind Computer Appears on National TV: Edward R. Murrow’s 'See It Now' program features the Whirlwind computer. Designed at MIT by Jay Forrester and a team of engineers, the computer was noted for its reliability: it had the capability to run 35 hours a week at 90-percent utility using an electrostatic tube memory (Williams Tube). The machine was started in 1945 and completed in 1951 and took up 3,100 square feet of floor space.

December 15, 1896 - Hollerith Agrees to Supply Machines for Russian Census: Hollerith’s Census Machine was first employed by the U.S. Census Bureau in 1890 as the result of a crisis in counting a rapidly-increasing U.S. population. Methods based on Hollerith's machine served for almost 60 years until the Bureau adopted electron.

December 16, 1925 - IBM-701 Team Member McClelland is Born: IBM-701 Team Member William F. McClelland is born in Bronxville, N.Y. He received a BS from MIT in 1947 and immediately joined IBM Watson Laboratory. At IBM he programmed the SSEC (Selective Sequence Electronic Calculator) for John von Neumann and was chairman of the Mathematics Planning Group in 1951-1953. This group developed computer specifications to solve complex mathematical problems, performed basic research in the use of a stored-binary calculator, and wrote and tested programs that were supplied to the customers of the 701. McClelland had held various management and marketing position at IBM until his retirement in 1982.
