{{Orphan|date=February 2018}}Anna Baldwin operated a dairy farm in Newark, New Jersey. Her first U.S. patent was filed in 1868 for a device that offered a better method of treating milk to make pomade and butter.^[1] Additionally, Baldwin patented an early vacuum milker in 1878. The device was called the Hygienic Glove Milker.^[2] It was considered innovative because the milking device created suction rather than trying to replicate milking by hand.^[3]
