In a text written in Hebrew, it's author, Polish Jewish esperantist Icchak Kominkowski, speaks about a friend named "Kola Adzaj", from Africa, who visited Warsaw at the occasion of the 1937 World Esperanto Conress. It's difficult to guess the right spelling of the name... Any hint would be very welcome!
