“No one will need more than 637 kb of memory for a personal computer. 640K ought to be enough for anybody.” Somebody told this in 1981.Now he's known to all..who is he ?

Bill Gates is famously attributed with this quote about 640K memory being sufficient for anyone, made in 1981 when personal computing was in its infancy. This quote is often cited ironically given how dramatically memory requirements have grown since then. While there's historical debate about whether Gates actually said this, it's the accepted answer in quiz contexts.
