David Raymond Layzer (December 31, 1925 – August 16, 2019) was an American astrophysicist, cosmologist, and the Donald H. Menzel Professor Emeritus of Astronomy at Harvard University.[2][3][4] He is known for his cosmological theory of the expansion of the universe, which postulates that its order and information are increasing despite the second law of thermodynamics.[5] He is also known for being one of the most notable researchers who advocated for a Cold Big Bang theory.[6][7] When he proposed this theory in 1966, he suggested it would solve Olbers' paradox, which holds that the night sky on Earth should be much brighter than it actually is.[8] He also published several articles critiquing hereditarian views on human intelligence, such as those of Richard Herrnstein and Arthur Jensen.[9][10] He became a member of the American Academy of Arts and Sciences since 1963,[11] and was also a member of Divisions B and J of the International Astronomical Union.[12] He died in Belmont at the age of 93 in 2019.[13]
