In 1964, Erling Mandelmann took a series of photographs of Le Corbusier's Villa "Le Lac" for Mobilia, a prestigious Danish design, interior and architecture magazine. The tenant of the Villa at that time was none other than the musician Albert Jeanneret, Le Corbusier's brother. The meeting between Erling Mandelmann and Albert Jeanneret led to a beautiful friendship. The photographer and the musician met frequently in the architect's "Petite Maison" - notably for a second series of photos in 1965, in which we discover Albert Jeanneret teaching eurythmics to his pupils. In addition to their artistic and documentary interest, these photographs allow us to see what the Villa "Le Lac" looked like when it was inhabited. To enter the intimacy of Albert Jeanneret is to enter the intimacy of Le Corbusier's architectural thinking and of one of his first "machine for living in".
