Something changed forever in a little school in Seattle in the early 1970s. Paul Allen met Bill Gates there, and from that moment on the duo would work together to start Microsoft in 1975. Well, it wasn't Microsoft at that time, it was "Micro-Soft". Eight years later Allen would have to leave Microsoft after receiving a Hodgkin's lymphoma diagnosis. He kept his shares at Microsoft -Gates tried to buy out them at $5 per share-, a decision that allowed him to become a billionaire, an investor and a philanthropist.

He invested in several companies and became a celebrated sports team owner. He purchased Portland Trail Blazers, Seattle Seahawks and Seattle Sounders FC, but he was also devoted to philanthropy, giving contributions worth more than $2 billion to several projects and organizations. He won all those battles and even beat cancer both in 1982 and in 2009. On October 1, 2018, Allen wrote on Twitter "Recently, I learned the non-Hodgkin's lymphoma I battled in 2009 has returned. I've begun treatment & my doctors are optimistic that I will see a good result. Appreciate the support I've received & count on it as I fight this challenge.". He finally didn't make it and died yesterday, October 15, 2018. RIP.
