Editor Van Griffith was the son of notorious industrialist "Griffith Jenkins Griffith" who shot his wife (but did not kill her) and served two years in prison for the crime. The elder Griffith was very generous to Los Angeles, donating a large swath of land for Griffith Park. He also in 1912 designated 100 acres of the park, at its northeast corner along the Los Angeles River, be used to "do something to further aviation". The Griffith Park Aerodrome was the result. Aviation pioneers such as Glenn L. Martin and Silas Christoffersen used it, and the aerodrome passed to the National Guard Air Service. (wiki)
