You've got to be crazy to want to stay up all night looking at stars...I get that a lot, and without taking sides on the 'crazy' issue, I can tell you that observing stars and analyzing starlight has got to be the best profession around.  Although I've been interested in stars since childhood, I seriously turned to astronomy after I finished my undergraduate degree in physics at the University of Wisconsin (1960).  Advanced degrees in astronomy from the University of Michigan were completed in 1966, with two intervening years spent at the Sproul Observatory studying parallaxes, proper motions, and binary-star orbits.  I was fortunate in finding a faculty position at the University of Western Ontario (1966-present).  There, with astronomers Bill and Amelia Wehlau and Jim Moorhead, we built a new astronomy curriculum and a new research observatory.  The Elginfield Observatory, as it came to be known, and its coudé spectrograph were pivotal in my research and in gaining background for the book.  After many years of teaching, observing, and publishing results from the Elginfield Observatory and elsewhere, the appeal of the profession has only grown.  Read my book 'Photospheres' and savor a taste of the stars.


Good News!  The 4th edition of 'Photospheres' (<-- click to see more) is in the publication stage and the figures in the electronic version are in full color.
