History
This section needs additional citations for verification. (January 2023)
The Gleason Works, the machine shop that eventually evolved into the Gleason Corporation, was founded by Irish immigrant William Gleason in 1865 after his previous experience in other machine shops.
An important product came in 1874 with Gleason's invention of the first bevel gear planer, a planer with integral indexing head designed to specialize in planing bevel gears. Planers and indexing heads had been combined before, but never in the winning form factor that Gleason created specifically for gears.
Gleason's daughter Kate was integral to the company's early operations, along with brothers James and Andrew.
In 1927, Gleason Works again led the innovation in this market, as it was the first machine tool builder to create machine tools to cut hypoid gears (which are an advanced variant of spiral bevel gears).[2]
