Life

Inside title of the bound first edition of the Phonographische Zeitschrift from 1900 with sole indication of Georg “Rothgiesser” (“ss”) as the publisher

Around 1879 he invented a bottle filling device in Hanover, which is characterized by its simplicity and practicality. Around 1881 he received a patent for a glass dome, which lowers when the candle burns.

From 1881 to 1888 he lived in Bielefeld . Here he was initially an assistant at the Dürkopp works. He was a founding member of the Bielefeld Velocipid Club, which was launched in 1882. In 1883 he co-founded the Richard Nagel & Co cycling equipment factory . He also took part in the construction of a cycling track and won high wheel races himself . In 1886 Rothgießer became the first editor of the specialist magazine Rad-Markt, which is still published in Bielefeld today . In the same year he invented a saddle-steered bicycle.

In 1887 he married Anna Stern.

In 1896 he produced compressed gas in Düsseldorf by compressing luminous gas with the help of pressurized water from a water pipe , with which he obtained brightnesses of 600 candles with double incandescent mantles .

At the end of 1904 he and his brother Heinrich founded Rossstrasse in Berlin. 6, his publishing house Nec sinit Gesellschaft für Technik mbH . Heinrich also ran the Rothgiesser & Diesing A.-G. publishing house with Karl E. Diesing (Berlin, Ritterstrasse 72). who, among other things, published the Phonographische Zeitschrift (trade journal for the record and speaking machine trade) from 1902 to 1938 , and for which Georg worked as a journalist. As such, he was in 1929 on the 25th anniversary of the company of Carl Lindström .

Around 1906 he received a patent (patent no. 161 112) for his device for regulating the gear of the motor on motorcycles.

Around 1908 he developed a "process for the production of translucent, colored photographs from negatives, which are produced using color rasters".

On April 15, 1908, the industrialist Karl Lanz announced the Lanz Prize of the Air, named after him, amounting to 40,000 gold marks. The later winner Hans Grade had completed his monoplane Libelle in the late summer of 1909 , but his practice area was too small. Rothgießer, who had acquired a plot of land in Bork (today Borkheide ), introduced himself to him as a real estate agent and promised to set up an airfield on a 50 hectare site. Just three days later, on August 17th, Hans Grade began his first flight attempts on the Marsfeld . It extended from Neuendorfer Strasse to the cemetery over a length of 1050 m and a width of 500 m. By setting up an airfield, Rothgießer wanted to attract Berliners to sell his forest properties.

Daughter Gertrud (* 1888 in Bielefeld; † 1944 in Auschwitz) became a pediatrician and had her first practice in her parents' apartment on Martin-Luther-Str. 91. After he had sold his Nec sinit Gesellschaft für Technik mbH in 1926, he bought her a house in the Tempelhofer Feld settlement that was built in 1920-28 . After the windows were broken in January 1933 and the walls were smeared with swastikas, she emigrated to Czechoslovakia and built her children's home in Marienbad . When the German troops marched in, she fled to Prague , but was deported to Theresienstadt in 1941 and murdered in Auschwitz in October 1944, shortly before the gassings ceased there in November.

A stumbling block was laid in front of Graumannsweg 48 in Hamburg-Hohenfelde for Emmy , a niece of Georg Rothgießer .
