RIP James B. Kaler

World renown lover of the stars and Professor of Astronomy, James B. Kaler has now gone onto that grand cosmos that was his home while he was with us. Jim Kaler quietly passed away from complications related to Parkinson’s Disease at the age of 84 at his home on November 26, 2022.

There are now many tributes to him but one of the most poignant was this, posted to the Department of Astronomy’s home page at the University of Illinois, U-C: https://astro.illinois.edu/news/2022-11-30/prof-james-b-kaler-1938-2022

With a career spanning almost 60 years, he had authored many books. It’s hard to imagine how one would have the time to be such a prolific writer and maintain a full-time professorship at one of the most prestigious Astronomy departments in the country and in the world. A quick read of the comments, published with his obituary below, will give you a glimpse into what kind of teacher -and individual he was – he was the salt of the earth and one in a million.

Of all of his books, I was particularly fond of Stars and Their Spectra available for free reading at the web archive here: https://archive.org/details/starstheirspectr0000kale_h1z4/page/n1/mode/2up. The hardcover edition is available here and in the list below:

In addition to his many books, he maintained an online compendium of almost a thousand stars here: http://stars.astro.illinois.edu/sow/sowlist.html

The university still maintains his faculty page here: http://stars.astro.illinois.edu/

Jim Kaler was one of a kind, a member of a quickly vanishing breed, a teacher of teachers, individuals who are imbued with a set of values and insight that are largely gone today. He studied under some of the best minds of the 20th century and will be sorely missed. Who will fill the shoes of these great ones who are passing so quickly?
