Who is the father of the personal computer?

Henry Edward Roberts coined the term "personal computer" and is considered to be the father of modern personal computers after he released the Altair 8800 on December 19, 1974. It was later published on the front cover of Popular Electronics in 1975 making it an overnight success. The computer was available as a kit for $439 or assembled for $621 and had several additional add-ons such as a memory board and interface boards. By August 1975, over 5,000 Altair 8800 personal computers were sold, starting the personal computer revolution.
