Bruce Hyde, best known to Star Trek fans as Lt. Kevin Riley, died Tuesday after a battle with throat cancer, according to a statement released by St. Cloud State University where he had been a professor. He had spent his last days at Quiet Oaks Hospice Center. He was 74.

His acting career included  Broadway and TV shows such as That Girl, Dr. Kildare and The Beverly Hillbillies.

As Kevin Riley, Hyde was only in Star Trek for two episodes in the series’ first season, but his role — which included a particularly memorable rendition of the song I’ll Take You Home Again, Kathleen — earned him recognition for the rest of his life.

Reticent to talk about his time on Star Trek for decades, he did comment to the St. Cloud Times that he thought “Trek” creator Gene Roddenberry’s vision of peace is the reason the franchise still has so many fans about 50 years later.

In addition to his acting career, Hyde earned a master’s degree in communication studies from North Texas State University and a doctorate in rhetoric from the University of Southern California. He joined the faculty at St. Cloud State in 1990, where he taught until his retirement this year.

Hyde, who lived near Rice, is survived by Saetre, two stepchildren, Ben (Sabrina) and Tim Saetre, granddaughter Joliva Jacobs, and by his sister, Janie Hyde Miller, and her husband, Riley Miller. Saetre said they are planning a private service.
