Our history now progresses to a large Congress in 1960. Readers who look through the program of the London Congress of 1960 will be impressed with the vitality of the Congress at that time, and with the spectrum of science represented there. Of the 235 participants, a few are named in Figure 5. Some of these outstanding biometeorologists are described in this history. At the time of this writing in 2007, five of the participants designated on the chart are still living and active. To make a comparison, there were about 250 attendees at our 50-year Congress. Examination of the 1960 Congress is important because the attendance at that meeting indicates the vigor and enthusiasm of the scientists contributing to a new, developing, interdisciplinary field. Another reason for emphasizing this particular Congress is the spectrum of countries represented by the attendees, extending from Sweden to the United States to South Africa.
