“...Enjoying the Cool Breeze and Starry Sky with Orion Right Overhead” From the diary of Th. Dobzhansky, 1949, Brazil

We provide diary entries of Theodosius Grigorievich Dobzhansky, an outstanding Russian-American geneticist, evolutionist, and entomologist, that were made in the spring of 1949, during his trip to Brazil. The trip was conducted to study genetic variability in natural populations of several species of the Drosophila fruit fl y and to determine the features of its ecology and behavior. In these notes, as well as in the notes made during his other expeditions, Th. Dobzhansky appears not only as a naturalist and a traveler, but as a person deeply and vividly interested in the way of life, customs, and views of other people, as well as the cultural, social, and political environments of the places he visited.
