RENO, Nev. (AP) — The longest-serving president in the history of the University of Nevada, Reno has died.

Joseph Crowley's daughter, Theresa Crowley, confirmed he died in Reno on Tuesday at the age of 84.

He was hospitalized earlier this month with pneumonia.

Crowley served as president of UNR for 23 years, from 1978 to 2001. He was president of the NCAA from 1993-95.

Crowley also served as interim president at San Jose State University for a year after his formal retirement in January 2003, and later returned to that role at Nevada from December 2005 to June 2006. He first joined Nevada's political science faculty in 1966.

Most recently, he worked as president of one of northern Nevada's first medical marijuana dispensaries.
