Gabrielle Oppenheim-Errera, wife of physicist Paul Oppenheim, first met BR at a logic conference in Paris sometime between the World Wars (i.e. 1935). BR stayed with them twice in the USA: the first time was sometime after he left the Barnes Foundation and the second was when the announcement was made that he had won the Nobel Prize (i.e. 1950). On Sunday mornings the couple with BR would visit Albert Einstein.

BR gave a Nobel Prize interview to the Trenton Times.
