Why Is Harold Zirin Influential?

According to Wikipedia, Harold "Hal" Zirin was an American solar astronomer also known as Captain Corona to a generation of Caltech Astronomy students. Life Most content from 1998 interview with Zirin Born in 1929 to immigrants from Russia and Austro-Hungary in Boston, Zirin grew up in Bridgeport, Connecticut. While attending Bassick High School, Zirin's home-built telescope won him a Westinghouse Prize, a Pepsi-Cola Scholarship, and scholarships to Harvard University as class of 1946 Valedictorian. Zirin earned his Bachelor of Science from Harvard in Applied Physics and completed his Astronomy Ph.D. in 1953. During his college years, Zirin played for the Harvard football team, participated in the hammer throw, and spent his summers working on the family's chicken farm in Vineland, New Jersey.
