Considered beacons of Danish design tradition, Mogens Lassen and Flemming Lassen were seemingly born to be architects, showing fascination with surveying and sketching buildings at a young age. The Lassen brothers garnered a lifetime of recognition and awards for their work within design and architecture, leaving a lasting mark on Danish design particularly within the study of Functionalism. 

The brothers went on to create numerous designs for particular buildings and homes that were never introduced to the public. An extensive archive of these designs and architecture are displayed in the Danish Natural Art Library. Created to share the Lassen brothers' design legacy, by Lassen carefully selects archival furniture designs to reintroduce to the world.
