378204 Bettyhesser           Discovered 2006 Dec. 26 by D. D. Balam at Mauna Kea.
Betty Hinsdale Hesser (b. 1938), passionately curious about, and gifted in languages, music and science, generously shares in an easily accessible manner her extensive knowledge, particularly about astronomy and reptiles, with people of all ages to address common misunderstandings and stimulate broader comprehension of nature.
