SUNDAY, JUNE 10: MAIL WITH WINDOWS
Profile America - Sunday, June 10th. A patent was granted on this date in 1902 for something that most of us would rather not see - an envelope with a transparent window in it, usually meaning a bill. The inventor, Americus Callahan of Chicago, called his idea the "outlook" envelope. The idea caught on quickly, as businesses discovered that it saved them the expense and time of addressing each envelope - since the address on the letter it contained could be seen through the window. The year Callahan's invention was introduced, there were nearly 76,000 post offices around the U.S. While the amount of mail has grown enormously since then, there are now just over 27,000 offices. You can find these and more facts about America from the U.S. Census Bureau, online at www.census.gov.
