Bruce Charles Heezen (//; April 11, 1924 – June 21, 1977) was an American geologist. He worked with oceanographic cartographer Marie Tharp at Columbia University to map the Mid-Atlantic Ridge in the 1950s.
Heezen was born in Vinton, Iowa. An only child, he moved at age six with his parents to Muscatine, Iowa, where he graduated from high school in 1942. He received his B.A. from the University of Iowa in 1947. He received his M.A. in 1952 and a Ph.D in 1957 from Columbia University.
Heezen collaborated extensively with cartographer Marie Tharp. He interpreted their joint work on the Mid-Atlantic ridge as supporting S. Warren Carey's Expanding Earth Theory, developed in the 1950s, but under Tharp's influence "eventually gave up the idea of an expanding earth for a form of continental drift in the mid-1960s." Tharp was Heezen's assistant while he was a graduate student and he gave her the task of drafting seafloor profiles. When she showed Heezen that her plotting of the North Atlantic revealed a rift valley, Heezen dismissed it as "girl talk". She persisted and they eventually discovered that not only was there a North Atlantic rift valley, but a mountain range with a central valley that spanned the earth. They also realized that the oceanic earthquakes they had been separately plotting fell within the rift, a revolutionary theory at the time. He presented this mid-ocean rift and earthquake theory at Princeton in 1957. At that lecture, preeminent geologist Harry Hess told Heezen, "Young man, you have shaken the foundations of geology!"
