Thomas Gilbert Pearson (1873–1943), was an American conservationist and one of the first faculty members at the University of North Carolina at Greensboro. He was a founder of the National Association of Audubon Societies, which became the National Audubon Society.
Pearson grew up in the woods of central Florida, having moved there at the age of 9 from Dublin, Indiana. He lived in a log cabin with his family of 3 brothers, 3 sisters, and his parents. The Pearsons were members of the Society of Friends. Encouraged by an older friend, Pearson began egg collecting. This hobby caused him to play truant from school, which was one of the reasons for his bad school record.
At 13, he bought a gun, which he had long desired to own. He learned that he could earn .90 to $1.25 by killing egrets to sell their plumes. He also made money by selling many birds' eggs.
After learning how to mount birds, he gathered quite a collection. He wrote to many schools and colleges, hoping to secure admission and pay for his education with his collection. At the age of 18, in 1891, President Lyndon Hobbs of Guilford College accepted Pearson's offer. In return, Pearson received board and tuition for two years if he would also collect and mount birds for the College. At the end of 2 years of college, Pearson was given a scholarship to continue his studies at Guilford. During his years at Guilford, he became editor of the college magazine, president of his literary society, manager of the baseball team, and captain of the football team.
After graduating from college, Pearson decided to devote his time and energy to arousing the people of North Carolina to the idea of protecting their fast-declining bird life. He then became a biology teacher at Guilford College. He also met Elsie Weatherly during this time. The two married in 1902.
In 1901, Pearson accepted the chair of biology and geology at the State Normal and Industrial College in Greensboro (now the University of North Carolina at Greensboro). He took his classes on walks in the outdoors, believing this to be as important as laboratory work with a microscope. During this period, he published his first book, Stories of Bird Life. The founder and first president of the National Association of Audubon Societies, William Dutcher, saw this book and encouraged Pearson to organize an Audubon Society in North Carolina. This he did in 1902, launching himself upon a course that would lead to influential work in state and national legislation.
