19 Feb 2014. Charlotte May Pierstorff (May 12, 1908 – April 25, 1987) was shipped alive through the United States postal system by parcel post on February 19, 1914. After the incident, parcel post regulations were changed to prohibit the shipment of humans.
On February 19, 1914, then 5 year-old Charlotte May Pierstorff was mailed from Grangeville, Idaho to Lewiston, Idaho to visit her grandmother C. G. Vennigerholz as this was cheaper than buying a train ticket. Charlotte, who weighed 48.5 pounds at the time, rode in the mail car with a 32¢ stamp on her coat. Leonard Mochel, May’s mother’s cousin and railway postal clerk, accompanied her during the trip and delivered her to her grandmother’s house. This event indirectly caused the United States Post Office to bar all humans and live animals from mail delivery with the exception of bees.
