David Roth: Pioneering Physician, Inventor, and Arts Patron

Early Life in a Changing Europe

David Roth was born in 1808 to a Jewish family in Košice, a city that was then part of the Hapsburg Monarchy in the Kingdom of Hungary. As Jews across Europe still faced intense persecution and restrictions at this time, the Roth family was one of the only Jewish households granted special permission to live within Košice‘s city walls. Unfortunately, David‘s father passed away when he was just 10 years old, leaving his mother Anna to support the family by running a kosher restaurant and inn.

Likely thanks to the patronage of Košice‘s Jewish community leaders, Anna was able to send all four of her sons to study in Vienna. There, David enrolled in the prestigious yet conservative Medical School in the 1820s, where recent advances like Samuel Hahnemann‘s homeopathic medicine were viewed with skepticism.

Medical Innovator in Paris

In 1831, David graduated just as a devastating cholera outbreak was ripping across Europe. He was dispatched to provide aid in rural Austria, but the epidemic also sparked violent anti-Semitic riots back home in Košice. Facing discrimination and violence, many Jewish professionals chose to emigrate – David Roth among them.

Armed with a letter of recommendation from Count Zichy-Ferraris, he set out for Paris in 1831. The cosmopolitan French capital was perceived as more enlightened and progressive, especially in contrast to the stifling climate Roth left behind. There, the young doctor established a thriving medical practice under the name Didier Roth and quickly earned acclaim for his embrace of the still-controversial homeopathic techniques.

Over the next decades, Roth released a series of influential publications on homeopathic medicine while also treating many luminaries of the Parisian cultural scene. His patients included pianist Frederic Chopin, poet Heinrich Heine, and members of the eminent Rothschild banking dynasty. From 1840-44, he even served a stint as the official physician to the Austrian Embassy in Paris.

From Medicine to Mechanics

In the early 1840s, Roth expanded beyond medicine to begin inventing an array of calculating machines and meters. It‘s unclear what exactly motivated this dramatic shift, but the mechanisms he created were impressive enough to earn recognition at Paris‘s National Exposition in 1844.

Roth showcased several arithmetic devices that could perform addition, subtraction, multiplication and division. While not wholly novel concepts, the judging committee was struck by the simplicity and reliability of Roth‘s creations:

"None of these machines is new in its intended purpose; but Dr Roth has solved these various problems by simple means worthy of interest."

For his calculating machines and other submissions like steam engine meters, Roth was awarded a bronze medal. But soon after this first flush of mechanical success, he returned to his thriving medical practice full-time. Homeopathy continued gaining legitimacy across Europe thanks to advocates like Roth publishing clinical research and demonstrating results with prominent patients.

Artistic Pursuits and a Legacy in Paris

Beyond his innovations in medicine and mechanics, David Roth was also tremendously passionate about the arts. He amassed an impressive collection of works, especially engravings by renowned German artist Albrecht Dürer. This collection would later be donated to the prestigious Bibliothèque Nationale in Paris.

In his later years, Roth‘s deteriorating eyesight ended his medical career and left him nearly blind. But he remained an active arts consultant for the powerful Rothschild family in France, contributing designs for engraving printing plates that were less susceptible to counterfeiting. He also produced ornate bronze clock cases and figurines.

David Roth died in Paris in 1885 at the age of 77, leaving behind a remarkable legacy across multiple fields. Hisgravestone can still be found in the city‘s famous Montmartre Cemetery, joined by his wife Anne Nathalie Sassary and stepson.

Through innovation and intercontinental migration, this Hungarian Jew achieved substantial success in his adoptive French homeland as a physician, inventor, author, and art collector. Roth‘s fascinating story reflects the era of social and scientific progress he inhabited, while also triumphing over the prejudices he initially escaped.
