As part of an attempt to dissolve a trust , thereby acquiring control of her third husband 's assets , Tita cast doubt on the paternity of Baron Georg Heinrich Thyssen-Bornemisza , alleging that his father was actually Count Iván Batthyány de Német-Ujvár , the husband of Thyssen 's sister , Countess Margit Batthyány . However , a settlement was reached between the parties before the baron 's death , which brought to a " peaceable " conclusion the wrangling over control of the vast Thyssen art collection , which is to remain in Spain , Hans Henrik having been the founder of the Thyssen-Bornemisza Museum in Madrid . One of the paintings in the museum , '' Rue Saint-Honoré in the Afternoon , Effect of Rain '' by Camille Pissarro , belonged to a Jewish couple who were forced to give it to the German government in exchange for an exit visa to the United Kingdom shortly after Kristallnacht in 1939 . By 2015 , their descendants had filed a lawsuit against the museum , on the grounds that it was stolen by the Nazis
