On Monday evening, Microsoft co-founder Paul Allen died of non-Hodgkin's lymphoma at the age of 65. At the time of his death, Allen was the 47th richest person in the world, with a net worth of $26 billion. For the last few decades of his life, Allen used his wealth for a staggering variety of business and philanthropic interests. In addition to owning the Seattle Seahawks and the Portland Trail Blazers, Allen founded a brain science institute, an AI institute, and Stratolaunch Systems, which was exploring private spaceflight.

Yet one of the research areas where Allen made the biggest impact was also the one he spoke about the least: the Search for Extraterrestrial Intelligence (SETI). Indeed, Allen almost single-handedly rescued American SETI by donating over $30 million to scientists scanning the cosmos for intelligent radio signals.
