ABSTRACT How are scientists made? How, as young adults, have they discovered a scientific vocation and career? Through formal schooling, typically; but in the field sciences also through practical apprenticeship—through work. This essay presents the story of a frontier farm lad who became a career naturalist as a hired collector of animal specimens in the American West. Family and work are the leitmotifs of Vernon Bailey's story. It was family farming—bringing in the hay and finding the cows—that connected Bailey's love (...) of skilled outdoor work with a desire to know nature scientifically. Traveling and working with professional naturalists, he came to see himself as a professional as well. His socialization was less a replacement than a layering of two identities, family and career.
