Big Apple
"The Big Apple" was popularized as a name for New York City by John J. Fitz Gerald in a number of horse-racing articles for the "New York Morning Telegraph" in the 1920s. The earliest of these was a casual reference on 3rd May, 1921:
Baldwin (apple)
According to S. A. Beach's "Apples of New York", the Baldwin originated soon after 1740 as a chance seedling on the farm of Mr. John Ball of Wilmington, Massachusetts, and for about 40 years thereafter its cultivation was confined to that immediate neighborhood. The farm later came into the possession of a Mr. Butters, who gave the name "Woodpecker" to the apple because the tree was frequented by woodpeckers. Deacon Samuel Thompson, a surveyor of Woburn, Massachusetts, brought it to the attention of Col. Loammi Baldwin, who propagated it and more widely introduced it in eastern Massachusetts. From Col. Baldwin's interest in the variety it came to be called the Baldwin.
