Why Is Donald Liebenberg Influential?

(Suggest an Edit or Addition)

According to Wikipedia, Donald Liebenberg is an American astronomer and adjunct professor in the department of physics and astronomy at Clemson University. An avowed eclipse chaser, he best is known for having traveled around the world to see 27 total solar eclipses since 1954. He is also regarded as having spent more time in totality, the darkest area within the Moon's umbra during a total solar eclipse, than anyone else alive.
