Alexander Prandtl

from Wikipedia, the free encyclopedia

Alexander Prandtl (* 1840 ; † March 17, 1896 in Dingolfing ) was a professor at the Agricultural Central School in Weihenstephan in the field of dairy farming.

Life

His father, Antonin Prandtl d. Ä. had a coffee shop in Untergiesing .

His siblings were:

  • Carl, studied fermentation chemistry and became an assistant at the Agricultural Central School in Weihenstephan
  • Antonin Prandtl the Elder J. (1842–1909), was a master brewer in Switzerland, then spent a long time in Hamburg around 1878 and returned to Munich in 1884, where he and Carl bought the Giesingheimer Bräuhaus, which went bankrupt ten years later. His son, Wilhelm Antonin Alexander Prandtl (1878–1956) became a chemist.
  • Anna, who married a magistrate.

After Alexander Prandtl had spent his student years in Munich, he rented a room from the merchant's widow Maria Ostermann to start work in 1869. Here he met 14-year-old Magdalene Ostermann, whom he married in 1874 when she was 18. The famous physicist and founder of fluid mechanics Ludwig Prandtl is his son. Another son and daughter died shortly after giving birth in 1877 and 1879. After several miscarriages in the following years, Magdalena spent the rest of her life in nursing homes and died in 1898. Alexander Prandtl retired for health reasons at the age of 52 and moved to his childless sister in Dingolfing, where he died in 1896.

Act

From 1870 to 1875, Alexander Prandtl mainly worked on the construction of the first continuously operating milk centrifuge. Eleven years earlier, his brother Antonin had published a work on this in the Polytechnic Journal, which he has now improved significantly. In 1875 he presented his skimming machine at the world exhibition in Frankfurt.

In 1876 he developed a new milk divider.
