DETTMER in London

Journal by BunyipBluegum

George DETTMER was a piano maker in London in the 1700s, setting up a business in Marylebone. We think he and his wife Ann came from Germany, but we don't know for sure. Has anyone researched this family?

His son, William David DETTMER, married Mary BETTS about 1775, and later her sister Phyllis Betts. Both in London. But where did the Betts girls come from?

The piano-making firm of George Dettmer and Son was founded by our George Dettmer at the very beginning of the Nineteenth Century. George was believed to have been born in Germany. The "son" was William Dettmer (b.1775), who ran the company for many years. In 1827 he took out a patent for a system for changing the pitch of a piano. Following financial difficulties in 1845, he migrated to Sydney where he established a branch of the firm.

There was a colony of German and Scottish piano makers in the Soho area of London, making square pianos like the Dettmer instruments illustrated here. (Other pianos of the "grand" variety were manufactured in the Cheapside district.)

Records reveal many Dettmers who called themselves "Pianoforte maker" from the 1750s throughout much of the nineteenth century. We must assume that they were related to George and William and that they were employed in the family firm.

Most of that seems to be pretty good without checking every single date.
I have seen the name Ann Robinson (for George's wife) on someone's tree, but I have never seen the evidence. I guess I was expecting a German name. Can anyone clarify this?
