Named in honor of pioneer frontier nurseryman John Chapman (1774-1845), also known as Johnny Appleseed, March 11th is celebrated for him. A second date of September 26th (his birthday) is also sometimes celebrated. The March date refers to the planting season.
John Chapman began his apprenticeship as an orchardist around 1805. He then traveled across Pennsylvania, Ohio, Indiana, Illinois, and West Virginia to plant apple nurseries. His orchards yielded fruit that was primarily used for producing hard cider, which back then was heavily consumed, in lieu of water, tea, coffee, juice, beer, and wine, according to Michael Pollan.
Devoutly religious, Appleseed believed that abstinence and exemplary behavior in his lifetime would lead to great rewards after death. He was a staunch supporter of animal rights, and according to popular tales, often favored the comfort and safety of animals and insects over his own.
