Who invented the potato wedge?

This seems to track back to the advent of "broasting" potato wedges in the 1950's,(Jo Jo Wedges in the NW USA about 1960), when broasting regular square fries would leave them completely crisped....the chunkier wedges (often with breading) would be cooked just right.

"Broasting is a trademark applied to a method of cooking chicken and other foods using a pressure fryer and condiments. The technique was invented by L.A.M. Phelan in the early 1950s and is marketed by the Broaster Company of Beloit, Wisconsin, which Phelan founded.
Broasting equipment and ingredients are marketed only to food service and institutional customers, including supermarkets and fast food restaurants. They are not available to the general public. The method essentially combines pressure cooking with deep frying chicken that has been marinated and breaded."

At a Saratoga Springs resort in New York in 1853, a customer complains that his fries are to thick. Chef George Crum fries up a serving of crunchy, crisp potatos, called Saratoga potato chips. Crum invents the potata chip. Source:
