Part of East Tremont is sometimes called Bronx Park South, particularly the section that lies immediately southwest of the Bronx Zoo. At one time, the land encompassing the neighborhood was owned by the Lorillard Family, known for the Lorillard Tobacco Company.

Starting in the mid 19th Century, East Tremont served as an intermediate step for immigrants from European farms and rural areas, as they climbed the social ladder from poor conditions of the Lower East Side slums to more hospitable neighborhoods. In 1848 the neighborhood attracted German farmers fleeing the Revolutions of 1848; during the 1870s it attracted Irish migrating from the Lower East Side or the famine in Ireland. Around the end of the nineteenth century, Italians spilled over from nearby Belmont, followed by Jews.

In 1950, East Tremont's population numbered an estimated 60,000, with about 441 persons per residential acre. The area was relatively integrated, with about 44,000 Jews, 5,000 Irish, and about 5,000 Germans and Slavs. There were approximately 11,000 "nonwhites" (mostly Blacks and Puerto Ricans) in the neighborhood, about 18% of the population.

East Tremont's large population of Jews had mostly migrated from Lower East Side slums, looking for a better neighborhood. The East Tremont neighborhood was modest but considered affordable and safe by its residents. Rents in 1950 were as low as $100 or even $62 per month for four rooms; comparable apartments in Jewish neighborhoods like Pelham Parkway closer to $350 per month. East Tremont Avenue was a bustling retail area with bakeries, kosher butcher shops, mom-and-pop candy stores, delicatessens, and clothing stores. While East Tremont contained no playgrounds, residents enjoyed easy access to nearby Crotona Park. The local Young Men's Hebrew Association was a center of civic life; it listed over 400 senior citizens and 1,700 families as active members. The schools were old and worn (PS44, the junior high school, had been built in 1901), but academic standards were high.

In his book The Power Broker, author Robert Caro devotes two chapters to the "One Mile" of the Cross-Bronx Expressway which ran through East Tremont. Caro argues that the expressway caused permanent damage to the neighborhood fabric. During the five years of construction, 5,000 residents were displaced and many stores demolished. The mile was completed in 1960. Quality of life in the neighborhood rapidly declined due to the noise and fumes from the highway, and physical fracturing of the neighborhood. By 1965, apartment buildings in the area around the expressway had become "ravaged hulks" with broken windows, graffiti, and broken plaster. Pipes were vandalized, staircases broke down, elevators stopped working, crime and vandalism had increased, gangs started to move into the area, addiction rates rose, and stores closed. An estimated 10,000 residents fled the neighborhood as it declined.
