In addition to work in the fields of ethnology, anthropology and cinematology, that has seen him carry the Explorers Club flag into far-flung places and visits to primitive people, he was the founder of the Club's Safari Dinners. These dinners were a popular feature of the lecture series for a long time. Some of the specialties at these dinners might be such items as: giant salmon (from Alaska); a variety of big game (provided by friends); cases of beer (from a Scandinavian source); and last, but not least, Carl's famous cream cheese and peanut butter spread dip. He also initiated many of the early annual dinners held at the Plaza, which were a great success.
