Oscar Mayo was born on January 25, 1851, in Pennsylvania, where he lived all his life. He died while playing a lawn game called quoits. Quoits was popular among coal miners and to this day the klink of quoits hitting metal stakes can still be heard in Pennsylvania backyards at picnics and family gatherings. Similar to horseshoes, players toss a ring onto a metal stake.
Oscar was playing quoits at his friends house on September 9, 1937, when he suddenly died. The cause of death was Coronary Thrombosis, a blood clot in the coronary artery. He was 86 years old. He was buried in Prospect Hill Cemetery in Peckville (Block 5, Lot 4-1/4).
