April 12, 1961 - the first human being in space, Yuri Gagarin. Rest In Peace, Yuri, you earned it.
He was a MUSICIAN, ASTRONOMER, EDUCATOR, CAT LOVER, ATHEIST, AND AMERICAN PATRIOT. Milo kept a lot of people thinking, learning and entertained for many years. He probably angered a few, too. No matter--he is sorely missed.
