![]() Bernhard Lauritz Frederik Bang |
death Bernhard Lauritz Frederik Bang Died 22 Jun 1932 at age 84 (born 7 Jun 1848). Danish veterinarian who in 1897 discovered Brucella abortus (Bang's bacillus), the causative agent of contagious abortion in cattle and of brucellosis (undulant fever) in human beings. Bang's teaching, with the introduction of antiseptics, represented a watershed in veterinary surgery. Although long recognized in human medicine, antiseptics had been met with little attention by veterinaries. Bang was instrumental in showing that tuberculosis could be transmitted by cow's milk and in developing isolation techniques. He was the first to use tuberculin, discovered by Robert Koch in 1890, on cattle. He used it diagnostically, rather than therapeutically, as a means for liberating livestock of tuberculosis and to create clean breeding centres. |

death Sir William Willcocks Died 29 Jul 1932 at age 79 (born 27 Sep 1852). British civil engineer who proposed and designed the first Aswan (Assuan) Dam (1898-1902) on the River Nile and executed major irrigation projects in South Africa and Turkey. He was born studied engineering in India before moving to Egypt in 1883, becoming director-general of reservoirs. On being asked to find a means of storing Nile water to allow the growth of an extra crop of cotton, he found a depression at Wadi Rayan, into which part of the annual flood waters could be diverted, then fed back into the river in the dry season. When persuaded to build a dam, he designed the Aswan Dam to allow the silt-laden waters of the early weeks of the annual flood to pass through, and only capture for storage the clear water that flowed later in the season. |

death Maximillian Franz Joseph Cornelius (Max) Wolf Died 3 Oct 1932 at age 69 (born 21 Jun 1863). Maximilian Franz Joseph Cornelius Wolf was a German astronomer who founded and directed the Königstuhl Observatory. He used wide-field photography to study the Milky Way and used statistical treatment of star counts to prove the existence of clouds of dark matter. He was among the first astronomers to show that the spiral nebulae have absorption spectra typical of stars and thus differ from gaseous nebulae. His most important contribution was the introduction of photography to discover hundreds of asteroids, the first of which he named Brucia in honor of the donor of his 16-inch double telescope, Catherine Wolfe Bruce. |
