On a trip to Italy in 1999, Amy Goldman, author of "The Heirloom Tomato from Garden to Table", brought home seeds of a tomato that impressed her. According to her book, she found it at a roadside grocery store near the Villa d’Este in Cernobbio, a town in northern Italy.
The tomato was similar in shape to Costoluto Genovese. In growing it out to de-hybridize it this variety emerged as the best. She honored her father by naming it after his family’s Brooklyn, NY store – Goldman’s Italian-American Grocery. The first listing in SSE was in 2008 – by Amy Goldman, of course.
Here is a video of a Google talk presentation Amy Goldman made about heirloom tomatoes:
