This is a sad day. Paul Allen certainly had many achievements, but one of his endeavors that I truly admire is the founding and funding of the Allen Institute [0], especially after I had the pleasure of attending Christof Koch's lecture at the American Academy of Neurology annual conference two years ago [1].

Thank you for everything. You are truly an inspiration. RIP.
