Basic Biographical Details

Name: Carl Roderique Louise Menni Bonn
Designation: Engineer
Born: 1858
Died: 19 October 1906
Bio Notes: Carl Roderique Louis Menni Bonn - the usual style of his name was Carl R Bonn - was born in 1858, the son of Dr Louis Menni Bonn, described as a professor of languages, and his wife Ernestine Cristina Dorotea Malmberg. Except that his family was based at Brighton and Taunton after it moved from Germany to Britain, nothing is yet known of his background and training. He woudl appear to have been working for Formans & MxCall in the mid-1890s. In 1897 he was taken into partnership by John Taylor Babtie, who was practising at 25 Castle Street, Dumbarton. Babtie was nine years his senior, born in Dumbarton on 18 October 1867, the son of John Babtie and Janet McLeod. He had been articled to Sir William R Copland from 1885 to 1890, thereafter becoming an assistant with Formans & McCall from 1894 to 1897 where he had met Carl R Bonn. Babtie had commenced independent practice in 1895.

In the same year that the partnership had been formed, it moved to 180 Hope Street, Glasgow. The following year Alexander Alban Hamilton Scott was appointed architect to the firm, which specialised mainly in bridge and reservoir work. The practice moved to 188 West Regent Street in 1905.

Bonn died suddenly near Mount Pleasant Farm, Kilpatrick on 19 October 1906. He was survived by his wife Florence Louise Carpenter and left moveable estate of 1,202 16s with a subsequent eke of 1,236 1s 8d, presumably represented by fees due at the time of his death. Babtie then merged his practice with the partnership of William Barbour Shaw and Hugh James Morton, the practice title becoming Babtie, Shaw & Morton.
