I have loved Hilary Knight’s illustrations for as long as I can remember. The words about Eloise, the little girl who lives in New York’s Plaza Hotel, were written by nightclub singer Kay Thompson. But the illustrations were by Hilary Knight, and I pored over them for hours because they were do detailed, witty, and expressive. Later, when I first read Mrs. Piggle-Wiggle, I recognized Knight’s penwork right away.

Lena Dunham (“Girls”) loves Eloise and Knight so dearly she has an Eloise tattoo. She spoke to the New York Daily News:

“I think so many young women were obsessed with Eloise’s unruly magic,” she said. “She’s just such a remarkably independent, vanity-free, complex little girl, and as a little girl you don’t see that many representations of yourself beyond a good little child with pigtails. So it was meaningful.”

And now she has made a documentary about Knight called, “It’s Me, Hilary,” that will be on HBO, premiering March 23, 2015.
