Poul Kjærholm (1929 –1980) began as a cabinetmaker’s apprentice and had a particular interest in various construction materials. After studying at the Danish School of Arts and Crafts, he worked briefly for Fritz Hansen, designing many notable chair prototypes. In 1955, Kjærholm began a lifelong partnership with manufacturer Ejvind Kold Christensen. After Kjærholm’s death, many of those pieces were handled by manufacturing firm Fritz Hansen. However, in 2004, Kjærholm's son established Kjærholm Productions, to produce those items of his father's furniture that Fritz Hansen had discontinued production of in 2003. Kjærholm’s designs are in the permanent collection of the MoMA in New York, the Victoria and Albert Museum in London, and other museum collections in Denmark, Norway, Sweden and Germany.
