Great Stork Derby
The Great Stork Derby was a period from 1926 to 1936 where women in Toronto competed to produce the most babies.
The race was the product of a scheme by Toronto lawyer and financier Charles Vance Millar who bequeathed the residue of his significant estate to the woman in Toronto who could produce the most children in a ten year period after his death.
It has been speculated that this bequest was meant to discredit the virtue of excessive births and promote birth control.
