Bernhard Lauritz Frederik Bang

Bernhard Lauritz Frederik Bang (June 7, 1848 Sorø - June 22, 1932 Copenhagen), was a Danish veterinarian. Discovered Brucella abortus in 1897, which came to be known as Bang's bacillus. Bang's bacillus was the cause of the contagious Bang's disease (now known as Brucellosis) which can cause pregnant cattle to abort, and causes undulant fever in humans.

Bang was awarded his M.D. in 1880 and began teaching at the Royal Veterinary and Agricultural University of Denmark in Copenhagen. He later became the director of the College. Bang was a veterinary adviser to the Danish government.

For his contributions to veterinary medicine, he received an honorary doctorate from the Veterinary College of Utrecht in 1921.

Bang is known for his work on:
 * development of a control for bovine tuberculosis
 * research on smallpox vaccination
 * research on animal bacillary disease
