Dr. Earle Haas patented the first modern tampon, Tampax, with the tube-within-a-tube applicator. Gertrude Tendrich bought the patent rights to their company trademark Tampax and started as a seller and spokesperson in 1933.[4] Gertrich hired women to manufacture the item and then hired two salesmen to market the product to drugstores in Colorado and Wyoming and nurses to give public lectures on the benefits of the creation and was also instrumental in instituting newspapers to run public advertisements.
