[Pharo-users] The Greatest Contributors to Smalltalk since 1980

I’m looking for a list of individuals who have contributed greatly to the advancement of Smalltalk, post Xerox PARC period (1972-1980). By advancement, I don’t only mean on a technical basis but on an educational or public awareness basis (this could include books, podcasts, talk circuit, video instruction, etc.). Any basis that has made Smalltalk a success in the marketplace (including commercialization). I posted this question on LinkedIn and got one useful response: the late James Robertson. My personal nomination is Kent Beck. I’m not that familiar with the deep history of Smalltalk, so I’m looking for more nominations. Thanks.
