The district attorney stared at the jury, unable to believe the "not guilty" verdict he'd just heard. Bitterly, he asked, "What possible excuse could you have for acquitting this man?"
The foreman answered, "Insanity."
The attorney responded, still incredulous, "I could understand that, but... all twelve of you?"

Albert Sauveur

Died 26 Jan 1939 at age 75 (born 21 Jun 1863).Belgian-born American metallurgist whose microscopic and photomicroscopic studies of metal structures make him one of the founders of physical metallurgy. In 1891 he began working with the South Chicago works of the Illinois Steel Company where, to follow his ideas, he was provided with a microscope and a room to work in. "This small beginning," Sauveur later wrote, "marked the introduction of metallography into the iron and steel industry of the United States." He is best known for his research on the hardening of steel (1893) that "the properties of steel rails were largely dependent on the dimensions of their microscopical constituents or grain sizes, and that in turn these dimensions resulted chiefly from the finishing temperatures."
