I first read about Fruitlands about 15 years ago. Before that I though veganism was a new concept, but really it has been around for at least 200 years or more.
If you aren't familiar with Bronson Alcott, he is Louisa May Alcott's father. She is famous for her book "Little Women".
I included a couple of quotes, click the link for the whole story.
The few months between June of 1843 and January of 1844 were some of the most important of Amos Bronson Alcott’s life. These were the months he and his family spent living in a utopian community he had cofounded to enable himself and his followers to create an example of perfect Transcendental living.
At Fruitlands, Lane advocated a strict policy of abstinence. “Neither coffee, tea, molasses, nor rice tempts us beyond the bounds of indigenous production,” Lane wrote. “No animal substances neither flesh, butter, cheese, eggs, nor milk pollute our tables, nor corrupt our bodies.” By living on a simple diet, the members of Fruitlands were to eliminate their need for trade and minimize labor.
If Alcott felt Brook Farm was not “austere enough,” he certainly made up for this lack at Fruitlands. Absolutely no meat or other animal products were eaten (hence the name Fruitlands). In fact nothing from animals (including wool, honey, wax, or manure) nor even animal labor were used by the community. The founders felt men should not take anything from animals, for they should be as free as humans. Bronson Alcott’s idealism was so strong, in fact, that he would not permit canker-worms to be disturbed, and forbade the planting of such vegetables and roots as grow downward instead of upward into the air.
Bronson Alcott’s eleven-year-old daughter, Anna, agreed with her father’s vegan beliefs. “We have power to think and feel with,” she wrote, “and they have not the same power of thinking, they should be allowed to live in peace and not made to labour so hard and be eaten so much. Then to eat them! Eat what has life and feelings to make the body of the innocent animals! . . . Besides flesh is not clean food, and when there is beautiful juicy fruits who can be a flesh-eater?”
