Alphonse Stengelin (1852-1938) was a French painter, engraver, and lithographer who spent much of his life working outside France. He is remembered mostly for his landscapes.

He was born in a home that had been designed by the architect Jacques-Germain Soufflot, designer of the Panthéon. His parents were Swiss.^[1][2][3][4] His father was a banker, associated with the banking house of Evesque & Cie.^[5]

After studying at the Collège-lycée Ampère, he enrolled at the École des beaux-arts de Lyon and became a student of the school's Director, Joseph Guichard. He also worked with Augustin Chenu and Florian-Némorin Cabane (1831-1922), both landscape painters.^[6] He spent much of his time copying the Old Masters at the Musée des beaux-arts de Lyon and was a great admirer of Rembrandt.^[5]

He eventually went to Paris and opened a small studio in Montmartre. From 1875 to 1910 he travelled extensively, visiting Germany, Switzerland and Italy.^[5] As the years passed, he spent more time in the Netherlands, where he not only painted but also produced engravings of his earlier paintings.^[7] The small towns of Hooghalen and Katwijk and the farming country of Bresse were among his favorite locations.^[5]

In 1888, he married his cousin, Coraly Stengelin (1860-1945) and they had four children. A street in Katwijk was named after him in 1907, after which he signed his works as "Stengelin van Katwijk".^[5] Until 1914, he divided his time between the Netherlands and a small house in Écully. In 1978, a "Place Alphonse Stengelin" was dedicated there.^[8]

He died in 1938 in Switzerland, where he had gone to live with his brother, Henri.

His works may be seen at the Musée des beaux-arts de Lyon, Musée des beaux-arts de Bordeaux, Musée des beaux-arts de Marseille and the Musée d'arts de Nantes.
