Can you help identify UW faculty in Brazil in 1967?

BrazilCALS soil scientist and department chair Alfred Hartemink is trying to identify the people in this photo, taken in Brazil in 1967­. The request for caption info comes from colleagues at the Universidade Federal do Rio Grande do Sul in Brazil, where the soil science department is celebrating its 50th anniversary.
