She was born Lucy Ridsdale in Bayswater, London, the oldest daughter of Edward Lucas Jenks and Esther Lucy Ridsdale. Known as "Cissie", she grew up with her sister and three brothers in the village in of Rottingdean, on the Sussex coast. Her brother Edward became a Member of Parliament for Brighton. She married Stanley Baldwin on 12 September 1892 in Rottingdean. Among the attendees were Stanley's aunt Alice and her son, Rudyard Kipling. The couple had seven children:
As a girl, she was a member of the White Heather Club, the first women's cricket club, founded in 1887 at Nun Appleton Hall near Appleton Roebuck, Yorkshire. It was on the field where she met her future husband. Apart from her home-making and raising of six children, she was also a formidable personality in her own right. She was very active and sociable, quite different from her husband in nature. Unlike her husband, she preferred the city life of London to the country. Their daughter Margaret Huntington-Whiteley said, "two people could not have been more unlike", but that "should they ever differ, it was always done quietly and politely." They shared the same deep Christian faith and moral outlook, and she was very supportive and encouraging of her husband. She often travelled with her husband during his time as prime minister, and she was an excellent speaker who found her own voice in politics. She was involved in the Young Women's Christian Association and other charitable bodies for women, especially those concerned to improve maternity care, after having herself suffered difficult pregnancies and the loss of her first child. In 1928, she became vice-chairman of the newly established National Birthday Trust Fund to address the high incidence of maternal mortality. Its original aims were to support maternity hospitals and contribute to the development of midwifery practice. In 1929, she helped found the Anæsthetics Appeal Fund with speeches, broadcasts and fund-raising. She was particularly concerned with reducing the pain of childbirth, and lobbied for new funds to make anaesthesia affordable for low-income women. Her work contributed to the passage of the Midwives Act 1936.
Death
She died suddenly of a heart attack in 1945 at Astley Hall, their country home in Worcestershire, She was cremated and her ashes were interred, with those of her husband, after his death in 1947 in the nave of Worcester Cathedral.
Legacy
In honour of her work for maternity care, philanthropist and cricket enthusiast Julien Cahn donated funds to build the Lucy Baldwin Maternity Hospital in Stourport-on-Severn, Worcestershire. It was commemorated by the prime minister on 16 April 1929, with a bronze dedication plaque over the main entrance reading. It expanded beyond maternity and became known as the Lucy Baldwin Hospital until its closure in 2006. In the 1960s, a new device that administered a combination of Nitrous oxide and oxygen for obstetrics, was named the Lucy Baldwin Apparatus For Obstetric Analgesia. Baldwin also wrote valuable notes of two major events in politics, the fall of the Lloyd George ministry and the Abdication Crisis.
