Pulitzer prize-winning journalist Brigid Schulte writes in The Guardian that the long stretches of time alone that creative geniuses—mostly men—afforded was facilitated by the dedicated women in their lives:
Anthony Trollope, who famously wrote 2,000 words before 8am every morning, most likely learned the habit from his mother, who began writing at age 53 to support her sick husband and their six children. She rose at 4am and finished work in time to serve the family breakfast.
From Wikipedia: Frances Milton Trollope wrote over 100 volumes, and her first book, Domestic Manners of the Americans (1832) is the best known. “She also wrote social novels: one against slavery said to have influenced Harriet Beecher Stowe, the first industrial novel, and two anti-Catholic novels that used a Protestant position to examine self-making.”
