What did Tom Kilburn do?
On August 11, 1921, English engineer Tom Kilburn was born. Kilburn became known for having written the computer program used to test the first stored-program computer, the Small-Scale Experimental Machine, SSEM, also known as “The Baby” in 1948.
What did Tom Kilburn invent?
computer: The first stored-program machines Williams and Tom Kilburn built a simple stored-program computer, known as the Baby, in 1948.
Where did Tom Kilburn live?
Manchester
He took early retirement in 1981 to care for his ailing wife, who was suffering from chronic bronchitis, but she died on 3 August 1981, two weeks before his retirement. After his wife’s death, Kilburn lived alone in the modest house they had shared in Manchester.
Did a Williams Kilburn tube store bytes?
The Williams-Kilburn tube, tested in 1947, offered a solution. This first high-speed, entirely electronic memory used a cathode ray tube (as in a TV) to store bits as dots on the screen’s surface. Ultimately, however, the unreliable Williams-Kilburn Tube proved a technological dead end.
How was software invented?
Software is a recent development in human history, and it is fundamental to the Information Age. The first generation of software for early stored-program digital computers in the late 1940s had its instructions written directly in binary code, generally written for mainframe computers.
What did Osborne invent?
portable computer
He created the first commercially available portable computer, the Osborne 1, released in April 1981. It weighed 24.5 pounds (12 kg), cost US$1795—just over half the cost of a computer from other manufacturers with comparable features—and ran the popular CP/M 2.2 operating system.
Who built Edsac?
Maurice Wilkes
EDSAC, in full Electronic Delay Storage Automatic Calculator, the first full-size stored-program computer, built at the University of Cambridge, Eng., by Maurice Wilkes and others to provide a formal computing service for users.
Who invented Williams Kilburn tube?
Tom Kilburn and Freddie Williams Inventors of the Williams-Kilburn tube, Tom Kilburn (left) and Freddie Williams (right), pose in front of the Manchester Mark I computer. This early random-access memory was used in several early computers.
How does Williams Kilburn tube work?
The Williams tube, or the Williams–Kilburn tube after inventors Freddie Williams and Tom Kilburn, is an early form of computer memory. The Williams tube works by displaying a grid of dots on a cathode ray tube (CRT). Due to the way CRTs work, this creates a small charge of static electricity over each dot.
Who is the father of software?
Watts Humphrey. Battle Creek, Michigan, U.S. Watts S. Humphrey (July 4, 1927 – October 28, 2010) was an American pioneer in software engineering who was called the “father of software quality.”
What machine did Adam Osborne ask Lee Felsenstein to build?
The History of Osborne 1: What to know The portable computer runs on the CP/M 2.2 operating system and is powered from a wall socket. Osborne 1 was designed by Lee Felsenstein and developed by Adam Osborne.

Who is Fredrick Calland Williams and Tom Kilburn?
Frederic Calland Williams. Tom Kilburn CBE FRS (11 August 1921 – 17 January 2001) was an English mathematician and computer scientist. Over the course of a productive 30-year career, he was involved in the development of five computers of great historical significance.
Who was John Kilburn married to?
Although Williams was initially disappointed at being given someone with so little practical experience, Kilburn became a valued member of the team. On 14 August 1943, he married Irene Marsden, a shop assistant. They went on to raise a son, John, and a daughter, Anne.
Where did Lord Kilburn go to school?
