Which street is named for an American entrepreneur and developer of the Garden District?

The correct answer is that the street named for an American entrepreneur and developer of the Garden District is McDonogh Street. This street is named after John McDonogh, a prominent figure known for his significant contributions to the development of this vibrant area in New Orleans during the 19th century. McDonogh was instrumental in promoting the growth of the Garden District, which is famed for its historic mansions and lush gardens, reflecting the wealth and prosperity of its time.

In understanding the significance of McDonogh Street, it's also important to note the other options. Marigny Street is named after the neighborhood of Faubourg Marigny, which has its own historical context, often associated with the Creole culture. Peters Street does not have the same historical significance tied to the development of the Garden District. Almonester Boulevard is named after Don Andrés Almonester y Roxas, an important figure in the Spanish Colonial era, but he was not directly involved in the development of the Garden District. Understanding the historical context and the contributions of these individuals helps clarify why McDonogh Street stands out in relation to the Garden District’s development.
