Hal Cowan studied business administration while playing music all through school. He loved playing organ and found himself in the company of fellow organ buffs as well as employees of organ stores and manufacturers. Hal worked for the Jenkins Hammond Organ Studios as president under Paul Jenkins who was a family member of the Jenkins Music Company. Hal took over the Hammond Studios as owner when Paul Jenkins left in 1977 and changed the name of the store to Jenkins Music Company (he licensed the name from J. W. Jenkins, Paul's brother). Hal owned the store along with his wife and offered some of the most innovative products during the great home organ boom of the 1960s and 70s.
