In addition to his musical credentials, Courboin held a degree in engineering; perhaps for this reason Courboin was throughout his life a great enthusiast of things fast, cars, boats and even airplanes. Courboin was among the first organists if his generation to actually own an automobile and at one time he owned a
Stutz Bearcat car equipped with an aircraft engine. Over the years Courboin was involved in several serious auto accidents, some of which affected his career as an organist. The most serious of these occurred on October 10, 1926, when Courboin was driving home from the Hickory Presbyterian Church. Shortly after midnight as he travelled down a major boulevard he misjudged the direction of a trolley car that made a left turn crossing his path and suddenly found himself unable to stop. The trolley car collided with Courboin's Lincoln tearing off the car's left running board and fender, smashing the windshield and demolishing the top. Courboin suffered severe lacerations to the face, fractured his jaw, lost some teeth and came close to losing his life. He was hospitalized for a full week and was forced to cancel important concert engagements for several months. Courboin served as tonal director for several prominent American organ building firms for whom he designed several notable instruments. Among these: • 1932
Kilgen organ (3/52) opus 4828 for St. Justin Church, Hartford CT. Courboin also performed the dedicatory recital. • 1934
