Diederich Friederich Georg Carl Heinrich Mahnke (1822-1895): Difference between revisions

<!-- From the Advertiser, Wednesday 4 September 1907:

<blockquote> Personal<p>

The death occurred at Cologne recently of Mr. Otto Boettger, the well-known Adelaide , optician and instrument-maker. The deceased, who was 65 years of age, was born in Elberfeldt, Germany, and came out to Australia in 1877. He had previously conducted a large business in St. Petersburg, but the venture not proving successful he determined to emigrate to Adelaide. His first engagement was with Mr. Dobbie cleaning old keys and repairing machinery. Starting in business for himself, his great knowledge of surveying and engineering instruments led the Government to place all their work in this department in his hands, and the results proved eminently satisfactory. About 10 years ago the business in Flinders-street was transferred to Mr. G. C. Kohler, who was an apprentice of Mr. Boettger's at one time, and had been with him nearly 30 years. Mr. and Mrs. Boettger then returned to Germany to spend the remainder of their lives in retirement. The deceased left no family. <ref>{{cite news |url=http://nla.gov.au/nla.news-article5089989 |title=PERSONAL. |newspaper=[[The Advertiser]]  |volume=L, |issue=15,251  |location=South Australia |date=4 September 1907 |accessdate=27 September 2023 |page=6 |via=National Library of Australia}}</ref></blockquote> -->
