The name "Henri" is the French version of the name "Henry." Both names have the same origin and meaning, which is "ruler of the household" or "estate ruler." The main difference between the two is the spelling, with "Henri" being the French variation and "Henry" being the English variation. Ultimately, the choice between "Henri" or "Henry" comes down to personal preference or cultural background. **

Henri Cavendish was a British scientist and physicist who lived in the 18th century. He is best known for his discovery of hydrogen, which he called "inflammable air," and for his work on the composition of water. Cavendish also made significant contributions to the fields of chemistry, physics, and geology. He was a very private person and often conducted his experiments in secret, leading to his reputation as a reclusive and eccentric scientist. **

Henri Becquerel died of unknown causes on August 25, 1908. It is believed that he may have succumbed to a stroke or heart attack, as he had been in poor health leading up to his death. Despite his groundbreaking discoveries in the field of radioactivity, the exact cause of his death remains uncertain. **

Henri Becquerel discovered infrared radiation in sunlight by conducting an experiment in 1896. He placed different colored glass filters over a thermometer and exposed it to sunlight. He noticed that the temperature of the thermometer increased even when the sunlight passed through a red filter, which blocked visible light. This led him to conclude that there must be invisible radiation beyond the visible spectrum that was responsible for the heating effect, which we now know as infrared radiation. **

Henri Becquerel did not discover infrared radiation in sunlight; he is actually known for his discovery of radioactivity. In 1800, Sir William Herschel discovered infrared radiation by using a prism to split sunlight into its different colors and measuring the temperature increase beyond the red end of the spectrum. This led to the discovery of infrared radiation, which is invisible to the human eye but can be felt as heat. **
