Of the 105 trades listed in Rose de Chantoiseau’s 1763 almanac of Parisian workshops, approximately two-thirds included widow mistresses…textile-type trades, such as bonnet makers, embroiders and drapers, included a large percentage of widows. However, several surprising trades included a large number of widows, such as glaziers, mirror-makers and book dealer-printers.
