Andrew Grove, one of the architects of semiconductor giant Intel's success, has died aged 79.
Mr Grove was the third employee at Intel and one of the leaders of its engineering team.
He helped the company move from making memory chips to processors, a decision that let to its dominance in the supply of chips powering PCs.
He served as chief executive of Intel from 1987 to 1998 and then became chairman of its board until 2005.

Born Andras Grof in Budapest, Hungary, he emigrated to the US in 1956 aged 20 after living through Nazi persecution, a Soviet siege, repression under different Communist regimes and the crushing of a popular uprising.
In the US, he taught himself English at the same time as he studied chemical engineering, earning a doctorate in the subject in 1963.
Straight after, he joined Fairchild Semiconductor and formed friendships with Gordon Moore and Robert Noyce.
Mr Grove joined the pair in 1968 when they left Fairchild to set up Intel, becoming the third employee at the fledgling semiconductor maker.
