Detmar Blow

Detmar Jellings Blow (24 November 1867 – 7 February 1939) was a British architect of the early 20th century, who designed principally in the arts and crafts style. His clients belonged chiefly to the British aristocracy, and later he became estates manager to the Duke of Westminster.

The fiction that he was a descendant of the English restoration composer John Blow was started in 1910 by Detmar Blow's wife Winifred, a member of the aristocratic Tollemache family, as a means of obtaining a licence from St Paul's Cathedral for the marriage of herself and Detmar.
