Dorothy Lathrop, 1923, Crossings by Walter de la Mare
Dorothy Lathrop (1891–1980) is by far the best-known illustrator from my Forgotten Illustrators series, but the majority of her work remains buried.
A few other fans have covered her life and work online, including BPIB:
Dorothy Pulis Lathrop was born April 16, 1891 in Albany, New York. One of the most influential and important illustrators of children's books in the thirties and forties, she began her career in 1918. At that time she was a 27 year old teacher of art in Albany. Arguably her most famous works were the illustrations for Rachel Field's Hitty, Her First Hundred Years, the story of a doll. [cont. reading]
Page Books has a good bibliography. I guess Nocloo is selling prints by Lathrop; they have a small gallery.
In her essay "Dorothy Lathrop's World," Anne Roberts discusses Lathrop's forty-five year career:
Her output was prodigious, even staggering. What makes this all the more impressive is the variety of media in which she worked: pen and ink, oil, watercolor, gouache, colored pencil, graphite, woodcut, wood engraving, lithographic pencil, and lithographic crayon. Each medium has its own exacting demand, and she mastered them all.

Apparently Lynd Ward used lithographic crayon for his Beowulf.
In summing up Mr. Bumps in her foreword, Lathrop nails Walter de la Mare's view of the world, a view she obviously shares:
I wonder if this perfect story, this humorous and poignant tale of a little super monkey is not as well a clear-sighted glimpse of the spirit of any creature as it tries without bitterness to adapt itself to our wishes and our strange, incomprehensible ways.

I love this one: it kind of hurts my head but I can't look away. I hope it gives you the eye-pop it gave me when the book arrived in the mail. (Purchased sight unseen; cheap copies are abundant online.)

from flap copy for Mr. Bumps: "For Jasper, Miss Lathrop used a monkey model which was secured especially for the illustrations of Mr. Bumps and His Monkey. The sensitivity and joy with which Miss Lathrop has drawn Jasper is evidence of her love and understanding of all animal creatures."

I used this last image back in March, but that version came from archive.org. This is my scan.
Thanks again to John Coulthart for turning me on to Lathrop in his comment to my post on De la Mare's Three Mulla-Mulgars (Lathrop's illustrations are the color ones at the bottom).
