In Memoriam: Lawrence G. “Larry” Tesler (1945-2020),
inventor of Copy/Paste at Xerox PARC, member of Apple Lisa team,
human-computer interaction expert

Tesler was a giant in the field of human-computer interaction, having pioneered modeless interfaces at Xerox PARC and carried those over to Apple as part of the Lisa team. While at PARC, he and Timothy Mott created a text editor called Gypsy that included the first implementation of the now-common Copy and Paste features for moving blocks of information easily within a document. According to Robert Scoble, Tesler was also on the committee at Apple that decided to re-hire Steve Jobs in the mid-1990s. He will be missed.
