Charlotte May Pierstorff (May 12, 1908 – April 25, 1987) was an American girl of German descent who was shipped alive through the United States postal system by parcel post on February 19, 1914.

[1][2][3] After the incident, parcel post regulations were changed to prohibit the shipment of humans.

Charlotte, who weighed 48.5 pounds (22.0 kg) at the time, rode in the mail car with a 32¢ stamp on her coat (equivalent to $10 in 2023).

[6] Leonard Mochel, May's mother's cousin and railway postal clerk, accompanied her during the trip and delivered her to her grandmother's house.

[7] This event indirectly caused the United States Post Office to bar all humans and live animals from mail delivery (with few exceptions, bees and day-old poultry amongst them).
