Served on little success
But Doug Engelbart’s invention has a sad back.

has subsequently been sold at least a billion Issues PC mouse.
Got medal by the President
And that’s not enough: In 1989, Engelbart was without the research lab and home. His house burned down with Doug and family shocked onlookers.

His daughter said her father died peacefully in his sleep.
