No abstract; this is the first paragraph:
Fred Keller came to Brazil in 1961, as a Fulbright Scholar, by chance. Some call it fate or destiny. From the North American side, it certainly took a lot of concentrated effort and the usual red tape. What happened on the Brazilian side of the cooperation is not clear. Writing on the subject, Keller said that a Brazilian student taking undergraduate courses at Columbia once asked him if he would like to visit Brazil. He said yes and later received a formal invitation, a letter signed by a dean of the University of São Paulo. However, arriving in São Paulo, Fred and Frances found out that the dean had been replaced and no one at the Department of Psychology knew that he was coming!
