Founding Fathers Kept in Touch Through U.S. Mail
Thomas Jefferson, shown on U.S. #590, had a long friendship with John Adams dating back to the years before the American Revolution. That friendship suffered after the bitter Presidential Election of 1802. But in 1812, they began writing letters to each other again in what has become perhaps the most famous correspondence in American history. They discussed philosophy, religion, and world events, as well as more common topics. The two friends died within hours of each other on July 4, 1826.
Rotary Presses Lead to Faster, Cheaper Production
Prior to 1923, the rotary press had been used in the production of coil stamps. It soon became apparent this was the fastest and most economical means of printing stamps. The rotary press could print 1000 stamps at a cost of .053 cents, compared to the conventional flat bed press cost of .08 cents. This difference of .027 cents is significant when one takes into consideration the fact that the Bureau printed millions of stamps each day.
Daily production rates jumped from 1,600,000 stamps on the flat bed press to 6,000,000 per day on the rotary press. Despite the increased production and lower costs, the Post Office Department was still skeptical. They finally decided a few stamps should be printed experimentally. At first, only the 1¢ Franklin was produced and used on a trial basis for six months.
The results were successful, proving that quality was not sacrificed for higher production. Shortly thereafter, the 2¢ Washington was produced on rotary presses as well. Eventually, new equipment was developed to improve the process, which resulted in the 1¢ through 10¢ being printed on the rotary press.
First US Inventors’ Day
On February 11, 1983, America celebrated its first Inventors’ Day.
Some nations had set aside days to honor their inventors before 1983 and some since. In January of that year, US President Ronald Reagan issued a proclamation establishing February 11, Thomas Edison’s birthday, as Inventors’ Day.
It’s custom in many countries to celebrate Inventors’ Day on the birthday of a noted native inventor. Reagan chose Edison because of his prolific career. Over the course of his life, Edison received 1,093 patents in the US (plus more in other countries) and founded 14 companies – including what would become General Electric.
In his proclamation, Reagan stated that “Inventors are the keystone of the technological progress that is so vital to the economic, environmental, and social well-being of this country. Individual ingenuity and perseverance, spurred by the incentives of the patent system, begin the process that results in improved standards of living, increased public and private productivity, creation of new industries, improved public services, and enhanced competitiveness of American products in world markets.”
