Peterson was born in
Jamestown, New York, a small, industrial city in western New York, on August 28th 1908. His father, Charles Gustav Peterson, was an immigrant from Sweden who came to America as an infant. At the age of ten, Charles Peterson lost his father to appendicitis and was sent off to work in the mills. After leaving the mills, he earned his living as a traveling salesman. Roger's mother, Henrietta Badar, was an immigrant, at the age of four, of German and Polish extraction, who grew up in
Rochester, New York. She went to a teachers' college, and was teaching in
Elmira, New York, when she met Charles. The two married, and moved to Jamestown, where Charles took a job at a local furniture factory. Peterson's middle name pays homage to his Uncle Tory, who resided in
Oil City, Pennsylvania, located south of Jamestown. Peterson graduated from high school in 1925 and went to work in one of Jamestown's many furniture companies. During his high school years, one of his teachers, Miss Hornbeck, had encouraged his interest in sketching and painting birds and nature, while he waited to earn enough money to purchase a camera. Several months after graduating, he traveled to New York City to attend a meeting of the
American Ornithologists' Union, where he met distinguished figures such as the artist
Louis Agassiz Fuertes and up-and-comers like
Joseph Hickey. Soon after, he moved to New York City and earned money by painting furniture, so that he could attend classes at the
Art Students League in 1927–1929 and later at the
National Academy of Design. He also managed to gain entrance to the eventually famous
Bronx County Bird Club, though not himself from the
Bronx. He hoped to attend
Cornell University, but his family's finances were not sufficient for the cost of tuition. Instead, he managed to obtain a position as an art instructor at the
Rivers School in
Brookline, Massachusetts. In 1934, his
A Field Guide to the Birds was published. The initial run of 2,000 copies sold out within a week. Peterson was married three times: briefly, to Mildred Washington, for 33 years to Barbara Coulter, with whom he had two sons, and for 20 years to Virginia Westervelt. His second and third wives contributed to the research and organization of his guides.
Virginia Marie Peterson developed the species range maps that were introduced in the fifth edition of
A Field Guide to the Birds of Eastern and Central North America. ==Career==
