He also thought that he had detected, in 1838, a magnetic action on steel needles by ultraviolet light, anticipating later discoveries connecting light and magnetism.
1896: Mathematician Wilhelm Ackermann born. Ackermann will discover the Ackermann function, an important example in the theory of computation.
2003: Physician and microbiologist Carlo Urbani dies of severe acute respiratory syndrome (SARS). Urbani identifed SARS as a new and dangerously contagious viral disease, and his early warning to the World Health Organization (WHO) triggered a swift and global response credited with saving numerous lives.
