Samuel Fedida (1918–2007) was a British telecommunication engineer responsible at Prestel for the development of Viewdata.[1]

Fedida had the idea for Viewdata in 1968 after reading a publication with the title The Computer as Communications Device. The first prototype became operational in 1974. In 1977 the system was introduced in the United Kingdom.
