John J. BittnerBorn 25 Feb 1904; died 14 Dec 1961 at age 57.John J(oseph) Bittner was an American geneticist who isolated a "Bittner milk factor" (1949) from the milk of certain mice, which strongly suggested that at least some viruses can cause cancer. Using carefully bred strains of mice, he compared the role of the mother's genetic disposition to be either prone to cancer or resistant. By having the mice of one disposition act as foster mothers and nurse the babies of the other disposition, he showed that cancer-prone young could grow to be cancer resistant. The opposite was also true: babies originally cancer-resistant became cancer prone. He published this observation (1936), and went on to isolate particles of a virus-like size from the milk of cancer-prone mice that were not present in the milk of cancer-resistant mice.
Devil at the congregation
One bright, beautiful Sunday morning, everyone in the tiny town of Johnstown got up early and went to the local church. Before the services started, the townspeople were sitting in their pews and talking about their lives and their families.
Suddenly, the Devil himself appeared at the front of the congregation. Everyone started screaming and running for the front entrance, trampling each other in a frantic effort to get away from evil incarnate.
Soon everyone was evacuated from the Church, except for one elderly gentleman who sat calmly in his pew, not moving, seemingly oblivious to the fact that God's ultimate enemy was in his presence. Now this confused Satan a bit, so he walked up to the man and said, "Don't you know who I am?"
The man replied "Yep, sure do."
Satan asked "Aren't you afraid of me?"
"Nope, sure ain't," said the man.
Satan was a little perturbed at this and queried "Why aren't you afraid of me?"
The man calmly replied "Been married to your sister for over 48 years."
