David Rockefeller’s Rolodex would put even the most popular of social media celebrities to shame, claims the Wall Street Journal (paywall). The man’s five foot-long, custom-built Rolodex housed 100k contacts, ranging from businessmen, astronauts, and celebrities, to global powerhouse heads and world leaders, including our very own late president Anwar Sadat. The Rolodex supposedly records their every interaction from the 70s on and even notes the date of Sadat’s assassination.
