"We are all survival machines for our genes."

"Bacterial genetics opened up the entire field of molecular biology."

"The phage group changed everything we thought we knew about heredity."

"Hard work never killed anybody."

"Work with purpose and integrity."

"Hard work pays off in the end."

"A man's gotta do what a man's gotta do."
