Leroy Grumman. His company was established in 1929 - the same year that Levitt and Sons was founded - and would go on to build as many fighter planes during World War Two as Levitt build houses in Levittown. After the Allied victory, his company spend decades manufacturing military aircraft to address national defense needs of the Cold War era.. One of the company's greatest triumphs, however, was building the lunar modules that put the Apollo astronauts on the Moon. Quite a number of Levittown residents worked for this company in the 1950's-1990's period and I have had the good fortune of knowing a few. PM
As a young naval lieutenant, Leroy Grumman was posted to the Loening Aircraft factory in 1920 as test pilot- company founder Grover Loening convinced Grumman to resign his commission and join his company, quickly rising through the ranks. In 1924, Loening hired two talented individuals to assist Grumman- Jake Swirbul and Bill Schwendler.
Financially faltering, Loening had to sell his company to Keystone Aircraft in 1928 which in turn got bought by Curtiss Wright. Curtiss planned to shut down the Loening factory in Manhattan and the employees had to move to Bristol, Pennsylvania.
Grumman and his two closest friends happened to be Jake Swirbul and Bill Schwendler. They didn't want to uproot their families so in 1929, the trio decided to form their own aircraft company and stay in New York City.
Since Grover Loening was barred from forming another aircraft company by the terms of the sale, the next best thing was to invest with Grumman. Loening's treasurer was hired as the first employee who also happened to be from a prosperous NYC family who decided to also invest with Grumman.
Leroy Grumman then recruited the thirty most skilled employees from the former Loening plant. Being financially cautious, Grumman decided they would only do business with the military, preferably the US Navy. To fund the new company, they opened a repair station for Loening amphibians on Long Island.
On 5 December 1929, Grumman and the founding associates met for the first time and the next day, the Grumman Aircraft Engineering Company was born. Most of the company's initial capital came from Grumman's severance package. Jake Swirbul's mother worked for a wealthy Long Island family that thought so highly of her, they lent him money as well.
In March 1930, the rest of the tiny company's employees were allowed to purchase stock.
At the maiden flight of the Grumman F-14 Tomcat on 21 December 1970, those initial investments in 1930 would have increased 7700x their original value!
Grumman's first design will the subject of a future post!
