(late 19th c, early 20th century)
The most likely candidate for creating Chicken a la King.
Greenwald, while at the Brighten Beach Hotel, New York in either 1898 or the early 1900s, prepared a special chicken dish one evening for the owners, Mr. & Mrs. E. Clark King II. The next day, either Mr. King loved it and wanted it on the menu or Chef Greenwald asked if he could put it on the menu. In either case, it was added to the menu as Chicken à la King ($1.25), and quickly became a great success.
