My brother-in-law Don Hunter, who has died aged 93, was a physicist who worked on some of the first electronic computers at Cambridge University and later helped set up one of the first major computer software companies in the UK.
Don worked as a research assistant in the Mathematical Laboratory in Cambridge from 1949 until 1952. There he was involved in pioneering work on the electronic delay storage automatic calculator (Edsac 1) computer. In 1955 he took up a research post at the Standard Telecommunication Laboratories (STL) in Harlow, Essex, where he was part of the design team for a computer called Step 1.
