“So many women are left out of historical records,” Dahlsad says. “Men will say, ‘I want to show off what my father did; he deserves to shine. Someone should do a book on him!’ Daughters don’t do that about their moms to the same degree, so often things get thrown away. How many men would look at their archives say, ‘Just take it all to the dumpster’? Somebody would be saying, ‘You can’t do that! You’re George Petty. Put it back!’”
