(Not the X-Files star!)

Born in Texas and raised in the South before he began life in the experimental and gay theatre circles of New York in the mid-1960s, working initially at the Caffè Cino. Using his adopted name Una O'Connor, Patrick worked as a typist in the city morgue during the day and in the theatre at night.

His first play, The Haunted Host, was produced at the Caffè Cino in 1964. When Joe Cino died in 1967, Patrick moved to the Old Reliable Tavern Theatre. A figure who resembles Patrick appears in many of his plays. He is "New York's most frequently produced playwright".
