Back in the mid to late 19th century, French ex-pat astronomical artist, Etienne Leopold Trouvelot, created these pastel drawings from his observations of planets and galactic occurrences. Years ago there was a fantastic exhibition showcasing his work at the Science, Business and Industry branch of the NY Public Library. Sadly, Trouvelot is known less for his artistic abilities and more for his earlier endeavors in entomology…gone very very wrong. We actually have him to thank for the scourge of Gypsy Moths in this country.
