Didier Roth

From Graces Guide
1841 'circular multiplying machine' at the Musée des Arts et Métiers

David (Didier) Roth was born in 1800 in Cassovia (Hungary)

The young Roth left to study medicine in Vienna. He later left for Paris, probably due to the anti-Semitic sentiment in Vienna.

For 30 years he practiced homeopathic medicine, with a wealthy Parisian clientele.

Roth was also an inventor of calculating machines and measuring instruments.

Between 1840 and 1844, Roth filed six patents.
