This must have been the start of the movement where, if you'd go to an auditorium, etc., often you'd see a sign that said, "Ladies must remove their hats." Of course this was back in the day when large ornate head coverings were the height of fashion. And many Menasha residents will know by instinct that this policy held no quarter with the Catholic church which for two thousand years required ladies to cover their heads until the policy was dropped in the 1980's.
By later in 1910, this "no hats" business failed to make headlines any more and, perhaps, the city went on to more pressing news. But for a short time, Menasha garnered state-wide attention for one of 1910's more frivolous stories.
