Life and achievements[edit]

Bruemmer left school in 1920 having acquired the O-level qualification. He learned the craft of watchmaking in Glashütte and took the trade test in 1924. His test work is now exhibited in the Museum of the School of Watchmaking in Glashuette. From 1927 to 1929 attended the German School of Watchmaking Bruemmer Glashuette. He studied at the Vocational Teacher Training Institute and the Graduate School of Berlin. From 1931 to 1933 he trained as a commercial teacher. In his thesis he wrote about "Vocational education in watchmaking." In 1933 he had a practical educational year at the trade school in Lokstedt-Niendorf. In 1934 he took on various teaching assignments in Hamburg and married in the same year his wife Gertrude. From 1 April 1936 he was fully employed teacher at the vocational school in Lokstedt-Niendorf. The monthly salary amount was then 236.37 Reichsmark. In 1940 he started as a teacher in the state sector School of Watchmaking Altona, Hamburg. In 1944 he became Commercial senior teacher at the same school. Since that time he wrote many technical articles for the journal "The clock" (organ of the Central Association of the watchmaker). [2] In 1952 he published the still used book "Applied Mathematics for Watchmakers" as the third edition of the textbook series "The Watchmaking School" of the publisher Hermann Brinkmann with the cooperation of the State School of Watchmaking in Altona and the "Central Association of the Watchmaker". In 1958 he was technical director at the state school for watchmakers in Hamburg-Altona, until he retired in 1968. Bruemmer died kidney failure many years after.
