Thaddeus William Harris first made his living as a physician and for many years thereafter as Harvard librarian. For six years, he also taught natural history in Harvard College - Henry David Thoreau was one of his students - but his desire for a full-time professorship was never realized.

Excerpt from Memoir of Thaddeus William Harris The difiiculties met with, at length led me to think of some means of making Entomology popular, and I looked to the young as' the proper sub' jects to begin with. With the hope that by exciting a taste among children for this branch of natural history, the parents might become interested also, I have rewritten my introduction in plain and simple language, divested as much as possible of all hard words, and intend to add to it brief descriptions of some of our most common insects. This you may think is small business, but I hope it may at least be useful and entertaining to those for whom it is intended.
