Big Apple
Although the history of "Big Apple " was once thought a mystery, a clearer picture of the term's history has emerged due to the work of amateur etymologist Barry Popik, and Gerald Cohen of Missouri University of Science and Technology. A number of false theories had previously existed, including a claim that the term derived from a woman named Eve who ran a brothel in the city. This was subsequently exposed as a hoax.
John J. Fitz Gerald
Fitz Gerald was the sports editor of the "Daily Sports Bulletin", a sports daily, in his later years. His last name was sometimes spelled "FitzGerald" by others, but "Fitz Gerald" was the spelling used in his "Morning Telegraph" column. He is best known today for popularizing "Big Apple" as a nickname for New York City.
