David Rockefeller’s Rolodex Was the Stuff of Legend. Here’s a First Peek

• thisisit 9y ago
  > Mr. Rockefeller recorded contact information along with every meeting he had with about 100,000 people world-wide on white 3-by-5-inch index cards. He amassed about 200,000 of the cards, which filled a custom-built Rolodex machine. He kept the 5-foot high electronic device at his family’s suite of offices in New York City’s Rockefeller Center for about half a century. 5 foot device just for rolodex cards. Wow.
