Tens of thousands of professional women built careers telling other women to stay home, often while someone else cooked and cleaned for them. Once members saw that they taught one way of living while practising another, they recognised that they had been propping up the very limits they had escaped.
When women were barred from most science and professional jobs, a field labelled as being about the home let them study chemistry, nutrition, and economics anyway. It also got them hired as professors, engineers, chemists, and businesspeople. The domestic label made the work acceptable, and the science underneath was real.
A movement that began as a serious effort to free the housewife from hardship and intellectual starvation drifted toward corporate work. Its members went to work for manufacturers, trade groups, and advertisers, and its science came to be used to sell factory products. The wish to become an industry pulled the field away from its founding purpose.
A field that opened doors for some excluded women shut them on others. Black women were left out of its founding meetings and barred from its Southern branches, even though they led much of its work and innovation.
A field can begin as an intellectual haven and end up less rigorous and more conforming, until people remember only its most trivial version. Today home economics calls up lopsided pillows and sunken muffins. That image hides a science of better living whose results, from standard clothing sizes to food safety, everyone now takes for granted.
