41 years ago today at UCLA, the first ever e-mail was sent. The message landed at Stanford University in Silicon Valley where decades later Google made home with the slogan "Don't Be Evil." The man behind phrase, and behind Adsense and Gmail, is Paul Buchheit.

And today, in celebration of the anniversary of e-mail, Buchheit, a current Facebook employee, donated $100,000 to Prop 19, the campaign to legalize marijuana in California.

"Silicon Valley is home to many of the largest contributors to the campaign to legalize marijuana in California," said Sasha Horwitz of the Yes on 19 campaign. "We believe this is indicative of a changing of the guard in political influence to a younger, tech generation."
