Roy Cockrum appeared at the Tennessee Lottery headquarters in Nashville Thursday to claim the prize. He is planning to accept a lump sum payment of $115 million.
Cockrum, 58, bought the ticket at a Kroger store in Knoxville on June 11. Before becoming a millionaire, he worked for 20 years as an actor and stage manager for theater and TV productions.
Cockrum says he is planning to use the majority of the money to start a foundation that will support performing arts organizations around the country.
Lottery officials say it's the largest prize ever won in Tennessee Lottery history.
