[3] According to Hull herself, "her father’s idea for bringing up children was to let his six youngsters read at will in one of the largest private libraries in Western Canada.

"[4] Upon reaching adulthood, Edna Hull found work as a private secretary in Alberta for a significant period of time.

[5] With the advent of WWII only four months after their marriage, the van Vogts moved to Ottawa in late 1939 so that Alfred could work for the Canadian Department of National Defence.

Van Vogt continued to write during his off hours, and sold numerous stories through May 1941, at which point he quit his day job and became a writer full-time.

After typing out many of her husband's stories in the early 1940s, Hull began to get ideas for her own science fiction and fantasy tales.

[1] After a year-and-a-half layoff from publishing, Hull's final story, "Bankruptcy Proceedings", appeared in the August 1946 issue of Astounding.

However, several of her previously published short stories were anthologized in the collaborative volume Out Of This World, a 1948 collection of works by both herself and van Vogt.
