Write a short paper (1-2 pages) about the life and work of a person who has contributed significantly to cosmological research since 1945. (Note that this excludes such people as Einstein, Hubble, and Lemaître, who lived beyond that year, but whose contributions were made before World War II.)

I would like each student to choose a different cosmologist, so contact me, via e-mail, office hours, or after class, as soon as you have picked someone, and I will record your choice or inform you that someone has already picked that person.
