Medicine

• August 15 – 1951 Pont-Saint-Esprit mass poisoning, a fatal outbreak, probably of ergotism, in southern France.
• Richard Asher describes Münchausen syndrome.^[11]

Physics

• Edward Teller and Stanislaw Ulam, working for the United States, develop the first thermonuclear bomb.

Psychology

• Solomon Asch begins publication of his conformity experiments showing how group pressure can persuade an individual to conform to an obviously wrong opinion.
