August Adler (mathematician)

from Wikipedia, the free encyclopedia

August Adler (born January 24, 1863 in Opava ; † October 17, 1923 in Vienna ) was an Austrian mathematician .

Adler attended school in Troppau and studied from 1879 at the TH Vienna and the University of Vienna , graduating in 1884 and gaining a doctorate. From 1885 he was assistant for astronomy and geodesy and from 1888 teacher at Döll's secondary school in Vienna, in 1890 supplement in Klagenfurt and in 1891 teacher at the German secondary school in Pilsen . In 1895 he became a professor at the German secondary school in Prague, completed his habilitation in 1901 and became a private lecturer at the German Technical University in Prague . In 1906 he became a private lecturer at the Technical University of Vienna and director of the Vienna State Realschule .

In 1906 he gave a new proof, guided with the help of inversions, of the theorem of Lorenzo Mascheroni (1797) that geometrical constructions with compasses and ruler can also be carried out with compasses alone ( theorem of Mohr-Mascheroni ). He published on descriptive geometry , algebraic geometry (higher-order space curves, ruled surfaces), drawing instruments, graphical solution of equations, and mathematics education.

In 1909 Adler published log tables .
