(Side-note: If Steve graduated high school in 1936 and entered college the next semester, his course of study would have been Fall 1936-Spring 1940; if he graduated in 1937 and entered the next semester, his graduation would have been expected in Spring 1941. His presence in a college course in the winter of 1941-42 strongly implies that he either entered college later in life, dropped out and re-entered, or otherwise pursued a non-conventional enrollment status, perhaps as a result of economic circumstances.)
