[3] As a young man he led an active and worldly life in the first decade of the 20th century, playing football at Harvard University, editing a Reform democratic newspaper in Port Chester, New York, and serving as commissioner of athletics for the AAU.

[2] Whitehead's supernatural fiction was partially modelled on the work of Edward Lucas White and William Hope Hodgson.

Lovecraft said of Whitehead: "He has nothing of the musty cleric about him; but dresses in sports clothes, swears like a he-man on occasion, and is an utter stranger to bigotry or priggishness of any sort."

[1] He died late in 1932, but few of his readers learned about this until an announcement and brief profile, by H. P. Lovecraft, appeared in the March 1933 Weird Tales, issued in Feb 1933.

[5] His work is still highly regarded today by writers and critics, and Stefan Dziemianowicz describes Whitehead's West Indian (mostly Virgin Islands) tales as "virtually unmatched for the vividness with which they convey the awe and mystery of their exotic locale".
