Allan Maxam (born October 28, 1942) is one of the pioneers of molecular genetics. He was one of the contributors to develop a DNA sequencing method at Harvard University, while working as a student in the laboratory of Walter Gilbert. Walter Gilbert and Allan Maxam developed a DNA sequencing method - now called Maxam-Gilbert sequencing - which combined chemicals that cut DNA only at specific bases with radioactive labeling and polyacrylamide gel electrophoresis to determine the sequence of long DNA segments.
