William Penhallow Henderson (1877 - 1943) was an American painter, architect, and furniture designer.

During Henderson's childhood, the family moved several times, settling in Turkey Creek, Texas in 1879 and in Clifton, Kansas in 1886.

Mrs. Henderson's book Anderson's Best Fairy Tales, illustrated by her husband, provided the funds for a second trip to Europe from 1910-1911.

In the following year, he designed the scenery and costumes for the Chicago Fine Arts Theatre production of Alice in Wonderland.

[1] In 1925 Henderson, with his first son-in-law John Evans, formed the Pueblo-Spanish Building Company, through which he designed and built many private homes and some public buildings, including the Railroad Ticket Office in Santa Fe.

The Santa Fe home of he and his wife, at 555-57 Camino del Monte Sol, is listed on the National Register of Historic Places as a contributing building in the Camino del Monte Sol Historic District.
