author
An illustrator and writer whose books brought history, science, and art to younger readers, he also built a long career as a painter. The surviving record is a little scattered, but it points to a versatile creative life that moved between publishing and fine art.
Available sources suggest that Henry S. Gillette worked both as an author and as an illustrator. An Internet Archive record credits him as the author of Leonardo da Vinci, Pathfinder of Science, published in New York by Franklin Watts in 1962.
Other catalog and bookselling records connect him with illustrated children's and educational books, and art-market listings identify a Henry Sampson Gillette associated with New York, Mexico, and Italy, with dates given as 1915–2003. Because these details come from a mix of library and marketplace sources rather than one full biographical profile, it is safest to say that he appears to have had a varied career spanning books, illustration, and painting.
