One of his first commissions was for the supply of roof windows for schools to convert loft spaces into classrooms. His concept was to “...make a skylight - a roof window - that is just as good as the best vertical window”. His first roof window was patented in 1942.
In 1952 Rasmussen formed a partnership with Ernst Günter Albers, owner of joinery company E. Albers & v. Drathen (ALDRA) in Meldorf, West Germany. They established VELUX GmbH Bauzubehör, with the word 'VELUX' being a combination of ‘VE’, short for ventilation and ‘LUX’, latin for light.
By the early 1970's, VELUX had grown to more than a thousand employees. It has since become a household name around the world, and the word ‘velux’ has become synonymous with a particular style of rooflight, in the same way that the brand name ‘Hoover’ is synonymous with the vacuum cleaner.
In 1992 Rasmussen’s eldest son, Lars Kann-Rasmussen, became Chairman of V. Kann Rasmussen Industri - the parent company of the VELUX Group. Villum Kann Rasmussen died in 1993 at the age of 84.
In 2016, the VELUX Group celebrated its 75th anniversary. Today, it has manufacturing and sales operations in more than 40 countries, and its products include roof windows, modular skylights, blinds, roller shutters, sun tunnels and remote controls.
