From Wikipedia, the free encyclopedia
Louis Albert Necker de Saussure FRSE MWS FGS (10 April 1786 – 20 November 1861) was a Swiss crystallographer and geographer.[1]
He is best remembered for devising the optical illusion now known as the Necker cube.[2]
Life
He was born in the Republic of Geneva, the son of botanist Professor Jacques Necker, nephew and namesake of statesman Jacques Necker, and Albertine Necker de Saussure.[3][4][5]
He was educated in Geneva, then sent to Edinburgh University in Scotland to study Sciences from 1806 to 1808.
The Necker cube is an optical illusion that was first published as a rhomboid in 1832 by him.[6]
He returned to Scotland in 1841 and settled on the Isle of Skye, lodging with the Cameron family at Bosville Terrace in Portree. His scientific interests turned to astronomy and a study of the aurora borealis. In 1843 and 1845, he was joined by his friend, James Forbes, a physicist and glaciologist. Together, they made the first accurate map of the Cuillins.[7]
He spent his later life mountaineering and collecting ornithological specimens. He died in Portree on 20 November 1861.[8] He is buried next to the Cameron family in the Portree churchyard.[7]
