Among the first children Anna Freud took into analysis were those of Dorothy Burlingham. In 1925 Burlingham, heiress to the Tiffany luxury jewellery retailer, had arrived in Vienna from New York with her four children and entered analysis firstly with Theodore Reik and then, with a view to training in child analysis, with Freud himself. Anna and Dorothy soon developed "intimate relations that closely resembled those of lesbians", though Anna "categorically denied the existence of a sexual relationship". After the Burlinghams moved into the same apartment block as the Freuds in 1929 she became, in effect, the children's stepparent.
