Special Feature:

Ralph A. Alpher (1921-2007) was a founder of Big Bang cosmology. His 1948 dissertation on primordial element abundances by neutron capture laid the foundation for modern big bang nucleosynthesis calculations, and led that same year to the prediction by Alpher and Robert Herman of the existence and present temperature of the cosmic microwave background radiation. The CMBR forms the crucial signature of a universe that began with a “Big Bang,” and its power spectrum has opened the era of “precision cosmology.”

We have been privileged to publish a three-part biography of Ralph Alpher, written by his son, Dr. Victor Alpher. We trust you will enjoy this glimpse into the life and work of Ralph Alpher.
