In this note, probably addressed to the committee responsible for awarding a prize of approximately 50,000 francs, Edmond Becquerel evaluates two inventions: he considers Zénobe Gramme's dynamo interesting, but derived from previous works (Pacinotti, de Romilly, etc.) and therefore unworthy of such a high prize; while Alexander Graham Bell's telephone seems to him a completely new advance, opening up a field of unprecedented applications already acclaimed by industry. Thus, he recommends refusing the prize to Gramme and awarding it to Bell.

Some translated excerpts

About the Gramme dynamo

"The Gramme machine does not seem to me to constitute a sufficient discovery to justify such a high reward, close to 50,000 francs."

"It's an induction machine, like those that existed before, but with a circular armature for the currents—Mr. Pacinotti and de Romilly had already built it."

"Giving Gramme a major award is acknowledging the supremacy of that machine, and that, to me, is not justified."

Regarding Bell's phone

"The telephone, on the other hand, can today be considered fully justified and useful from a practical point of view."

"There is a rapid, unrestrained demand for this device."

"If Mr. Bell hadn't made his telephone, we wouldn't have anything of value."

"The telephone is something completely new."

Edmond Becquerel was a 19th-century French physicist known for discovering the photovoltaic effect in 1839, a phenomenon in which certain materials produce electricity when exposed to light—the basis of modern solar cells. He also excelled in studies of fluorescence, phosphorescence, spectroscopy, and color photography. Without his discovery, advances such as radiotherapy, nuclear energy, and carbon-14 dating would not have been possible. Therefore, Edmond Becquerel is a true pioneer of modern physics, comparable to Röntgen with X-rays or Einstein with the theory of relativity. Although his son Henri received more recognition for discovering natural radioactivity, it was Edmond who paved the way for a new era of science.

The manuscript is fascinating for the history of the telephone because Becquerel argues that Alexander Graham Bell's telephone "opens up a radically new domain" and already sparks "rapid, unrestrained demand." In other words, the text documents the enthusiasm of a scientist in the face of the novelty of the telephone, at a time when many of his peers still hesitated about its practical usefulness, a rare snapshot of the scientific and industrial debate that preceded the massification of telecommunications, which occurred 120 years later.
