French photographer and botanist (1798–1872).
Louis Alphonse de Brébisson (25 September 1798 – 26 April 1888) was a French botanist and photographer born in Falaise, Calvados. In his youth, he was interested in mineralogy and entomology, but his focus soon turned to botany. He is renowned for "Flore de la Normandie", a work on vegetation native to Normandy that was published over multiple editions. He was the author of several papers on Diatomaceae and Desmidiales, and was possibly the only French scientist researching these algae groups at the time. He also conducted extensive investigations of mosses and orchids. With Christiaan Hendrik
