Regular readers might remember Cornelius Bennett Harness, who carried on a lucrative business in electro-magnetic products in London in the 1880s and 1890s. I have blogged about his Electric Corsets and the Ammoniaphone, an inhaler promising artificial Italian air to singers and public speakers. Harness’s showrooms, known as the Electropathic and Zander Institute, were on the corner of Rathbone Place and Oxford Street, and while I was in London the other day I went to have a look – it was interesting to see how little the place has changed.
