Carola Giedion-Welcker
Carola Giedion-Welcker (née Welcker; April 25, 1893, Cologne – February 21, 1979, Zurich) was a German-Swiss art historian. Life and work. Carola Welcker was born in Cologne in 1893, the daughter of a banker Carl Welcker (1848–1928) and his American wife Mary Legien (1865–1919). She studied art history in Munich under Heinrich Wölfflin, and in Bonn with Paul Clemen. She received her doctorate in Bonn in 1922. During her studies in Munich she met Sigfried Giedion, a Swiss fellow-student, and they married in 1919. In 1923 the couple met László Moholy-Nagy, who introduced them  to Hans Arp a year later. Arp interested her in the literature of Lautréamont, Rimbaud, and Jarry, and persuaded her to attend the 1925 Surrealists exhibition in Paris. Through Arp she met Piet Mondrian and Constantin Brâncuși, whom she visited in his studio in 1928. She later wrote a monograph on him. In 1925 the Giedions moved to Zurich. Their home became a meeting-place for modern artists such as Hans Arp, Sophie Taeuber-Arp, Kurt Schwitters and Max Ernst. Irish writer James Joyce was also one of her guests. Giedion-Welcker met Paul Klee in Bern and subsequently wrote  a biography of him. A year before her death in 1946, Paul Klee's widow Lily Klee specified in her will that the care of her husband's artistic estate should be overseen by a commission that was to include her son, Felix Klee, Carola Giedion-Welcker, and the Bern collectors Werner Allenbach, Rolf Bürgi, Hans Meyer-Benteli and Hermann Rupf.. Giedion-Welcker published about 280 articles in magazines on modern painting, sculpture and poetry. She also wrote 17 books, including "Moderne Plastik", "Poètes à l'Écart" and the anthology "Schriften 1926–1971", published in 1973 by Reinhold Hohl. In 2007 the  Kunsthaus Zurich dedicated an exhibition to Carola Giedion-Welcker, curated by Cathérine Hug. It showed how as an art historian, author, and curator, she shaped the cultural life of the city and influenced the gallery's purchasing policy. About 40 works including paintings, sculpture, graphics, photos and letters were exhibited.
