In November 1961, Eva Hesse married fellow sculptor Tom Doyle. In August 1962, Eva Hesse and Tom Doyle participated in an Allan Kaprow Happening at the Art Students League of New York in Woodstock, New York. There Hesse made her first three-dimensional piece: a costume for the Happening. In 1963, Eva Hesse had a one-person show of works on paper at the Allan Stone Gallery on New York's Upper East Side. By 1965 the two had moved to Germany so that Doyle could pursue an artist's residency from German industrialist and collector Friedrich Arnhard Scheidt, a move Hesse was not happy about. Hesse and Doyle, whose marriage was by then falling apart, lived and worked in an abandoned textile mill in Kettwig-on-the-Ruhr near Essen for about a year.. The building still contained machine parts, tools, and materials from its previous use and the angular forms of these disused machines and tools served as inspiration for Hesse’s mechanical drawings and paintings. Her first sculpture was a relief titled" Ringaround Arosie", which featured cloth-covered cord, electrical wire, and masonite. This year in Germany marked a turning point in Hesse's career. From here on she would continue to make sculptures, which became the primary focus of her work. Returning to New York City in 1965, she began working and experimenting with the unconventional materials that would become characteristic of her ouptut: latex, fiberglass, and plastic.
