Bronxville wasn't exactly an estate village, since it wasn't incorporated under Section 33. (What is Section 33? That's the law that allowed rich people to incorporate their tiny neighborhoods as villages, which we talk about in the first three episodes.) 

But, like estate villages, the village of Bronxville was the passion project of one man, a millionaire named William Van Duzer Lawrence. Biographers credited Lawrence's success to his thrift, prudence, and enterprise, but in fact he made his money selling a patent medicine called Fellows' Compound Syrup of Hypophosphites. Later in his career, Lawrence decided to pivot to property development. He bought 86 acres in the suburbs north of New York City, and invited artists and well-to-do professionals to live there. 

But not everyone was invited to live in Bronxville. Certainly not the people of Tuckahoe, an adjacent hamlet that had the idea to incorporate as a village...and who wanted to include the neighborhood of Lawrence Park, the artist colony that Lawrence considered his own.
