P&G（Procter & Gamble）さんのインスタグラム写真 - (P&G（Procter & Gamble）Instagram)「Happy #BlackHistoryMonth! Inventor Mary Kenner holds a special place in our hearts, as she is best known for her patent for a toilet tissue holder that made sure that the loose end of a roll was always within reach. She was a self-taught inventor who filed five patents throughout her career — more than any other Black woman in history. Mary’s other notable patents included sanitary pads, a carrier for a walker and a back washer that could be mounted on a shower wall. Join us in pausing to celebrate both Mary and the endless Black accomplishments, past and present, that we are fortunate to have benefited from.」2月26日 1時05分
