Name associated with Stadlman. Curiously, the brothers Allen and Malcom Loughead were going to have importance with the Lockheed company.

-In 1919 they settled in Santa Barbara, California. The factory superintendent was Antony Stadlman and John Northrop the engineer.

-The engine attributed to them is the XL-1 that gave 25 hp at 1,800 rpm, and was built around 1919-20. It was water cooled and had double ignition.

-It became known as a Loughead-Stadlman brand engine.

From Appendix 6: The twin-cylinder engine that would later be known as Lockheed - the famous brand that built aircraft - because Loughead changed his name.

-Allen Haines Loughead officially changed his name to Allen Haines Lockheed in 1934, but earlier, as early as 1926, he had founded the Lockheed Aircraft Company in Hollywood.
