Life

Julius Bodo Unger was born in 1819 in the Old Town of Hanover, before the union with the Calenberger Neustadt , before the end of the personal union between Britain and Hanover , before the transformation of Hanover for main and royal capital of the kingdom, and especially before the beginning of industrialization under King Ernst August .

When he was two years old, his father, the consistory secretary Friedrich Rudolf Bodo Unger (1777–1821), died on May 11, 1821. His mother Luise Friederike Henrietta Unger nee. Unger (1784–1855) arranged for a guardianship later, as did his brother Friedrich Wilhelm Unger (1810–1876) . This was taken over by Johann Andreas Wehner and did not end until 1843. In 1840 he began studying chemistry in Göttingen a. a. at Wöhler. In 1845 he was a student of Justus Liebig in Giessen . His scientific contributions in the reports on the negotiations of the Royal Prussian Academy of Sciences in Berlin as well as in the Annals of Chemistry and Pharmacy come from this time . For example, he provided information about the compounds of guanine , about "The conversion into carbon dioxide during the preparation of soda " and "About xanthine ". However, he ended his academic career in favor of entrepreneurial plans.

At the latest after the accession of King George V in 1851 Bodo Unger in that time still largely undeveloped had Nedderfeld in Linden (in today's district Linden-Nord ) on the leash land acquired, where he in 1852 a factory for soap factory was built, which he there Operated for more than three decades until 1886. As a self-employed entrepreneur and chemist, Bodo Unger also used the location of his property on the Leine to remove salt solutions and to produce gold sulfur .

Bodo Unger was admitted to the Masonic Lodge at Zur Ceder on April 15, 1858 under matriculation number 529 .

Today there is a children's playground on the site of the former Ungers chemical plant .

Unger was married and had two daughters and two sons.
