The Frenchman Louis Daguerre invented the daguerreotype, an early photographic process that used a iodine-sensitized silvered plate and Mercury vapor to produce photographs. Daguerre made this discovery by accident in 1835, and this photographic process was introduced to the public in 1839.
Louis Daguerre introduced daguerreotypes in 1839.
Nicephore Niepce is credited with inventing the photographic process, but not until 1825 after a few years of trying. The 18th century as you asked, is too early.

William Henry Fox Talbot (11 February 1800 - 17 September 1877) was the inventor of the negative / positive photographic process, the precursor to most photographic processes of the 19th and 20th centuries.
The calotype, an early photographic process, was developed by William Henry Fox Talbot in the 1830s, with the first successful photographic images created in 1834. It was patented in 1841 and allowed for the production of multiple copies from a single negative, marking a significant advancement in photography. This process laid the groundwork for modern photographic techniques.
Early photos were commonly referred to as "daguerreotypes," named after Louis Daguerre, who developed this first practical photographic process in the 1830s. These images were created on polished metal plates coated with light-sensitive materials and produced highly detailed, one-of-a-kind photographs. Other early photographic methods included calotypes and tintypes, which further advanced the art of photography.
A daguerreotype is a photograph made by an early photographic process. The photo was produced on a silver plate sensitized to iodine and developed in mercury vapor.

Braille is named after its inventor, Louis Braille. Louis Braille was French and developed the system in the early 19th century as a way for visually impaired people to read and write.
