In 1975 Wilfred Bion and I were invited by Professor Virginia Bicudo to spend the month of April in Brasilia. During that time Bion worked with individuals and groups, gave three lectures at the university, and took part in three panel discussions (entitled Brasilia, A New Experience) at the Buriti Palace to mark the fifteenth anniversary of the founding of the city. Panel members, representing the arts and sciences, dealt with aspects of the character of the city and the prob-lems involved in forming and developing a new community. I have included his contributions to these discussions.In April 1978 we spent two weeks in Sao Paulo - our third visit. Bion held fifty clinical seminars, daily consultations, and ten evening meetings (published in Bion in New York and Sao Paulo). Such a volume of work demonstrates his remarkable vigour and stamina at the age of eighty.
