10 September: Calder performs Cirque Calder at 7 Villa Brune. For seating, he invites spectators to bring their own boxes. (Hayes 1977, 238)

After 12 September: Louisa James visits Calder in Paris. (CF, Louisa to Mother, 7 September)

October: In need of money to pay rent, Calder charges admission to performances of Cirque Calder. I bought planks, pinched some boxes, and made bleachers. I handled thirty people an evening on, I believe, four evenings. At the end of my professional run, the concierge came and said the proprietor who lived in the front could not get to sleep on account of the cymbals. (Calder 1966, 113-114)

14 October: On the advice of Frederick Kiesler, a Viennese architect, Calder invites Le Corbusier, Karl Einstein, Fernand Leger, Piet Mondrian, and Theo van Doesburg to a presentation of Cirque Calder at 7 Villa Brune. To avoid conflicts, Kiesler insists that Calder send a telegram inviting Van Doesburg for the following night. (Calder 1966, 112-113; AAA, circus poster)

15 October: Van Doesburg and his wife, Petronella, attend a performance of Cirque Calder. I got more of a reaction from Doesburg than I had from the whole gang the night before. (Calder 1966, 112-113; AAA, circus poster)

Fall: Kiesler introduces Calder to composer Edgard Varese, and Calder makes a wire portrait of him. Varese, who feels that his own music resonates with Calder's new abstract sculpture, becomes a frequent visitor to Calder's studio. (Calder 1966, 125; CF, 1955-1956, 78)

October: Accompanied by another American artist, William "Binks" Einstein, Calder visits Piet Mondrian's studio at 26 rue de Depart. Already familiar with Mondrian's geometric abstractions, Calder is deeply impressed by the studio environment: it has a wall of large colored paper rectangles that can be repositioned for compositional experiments. Calder later recounts that this studio visit gave him a "shock" toward complete abstraction. For the next three weeks, he makes geometric, non-objective paintings. (Calder 1966, 113; CF, Calder 1955-1956, 78)

25 October-24 November: Calder exhibits nine works, including Le lanceur de poids and Femme Nue, at the "Association Artistique les Surindependants," Parc des Expositions, Porte de Versailles, Paris. (CF, exhibition file)

November: Therese Bonney photographs Calder in his studio at 7 Villa Brune. (NYPL, photography collection)

Fall: Louisa decides to marry Calder. I have just come home from a polo game with a not particularly entrancing young man, and I have decided that I am sick to death of going out with one person and another that don't interest me. I am sick of it chiefly because the only person that amuses me and has amused me for the last year and a half, is Sandy. The only thing to do to my mind is to make it permanent and get married, and the sooner the better.... To me Sandy is a real person which seems to be a rare thing. He appreciates and enjoys the things in life that most people haven't the sense to notice. He has ideals, ambition, and plenty of common sense, with great ability. He has tremendous originality, imagination, and humor which appeal to me very much and which make life colorful and worthwhile. He enjoys working and works hard, and thus ends the summary of his character. (CF, Louisa to mother, fall)
