He was then appointed assistant professor at Clemson College in South Carolina. In 1943 he joined the US Navy – serving in World War II as a Ltjg on the USS Chincoteague (AVP-24). He was a veteran of the battles of Peleliu, Iwo Jima and Okinawa. Near the end of WWII in 1945, he served as a peacekeeper in Shanghai China, helping the Chinese get the Japanese out of China.

Research
Hauser was best known for his research on biological efficiency of the life cycle of beef cattle with special emphasis on genotype x environment interactions. This research was conducted largely with identical twin cattle. He subsequently did studies that, for the first time, demonstrated that photoperiod modified the processes leading to puberty and postpartum fertility in cattle.
