Leslie Kenton (June 24, 1941 – November 13, 2016) was an American-born writer, journalist and entrepreneur who specialised in New Age health and beauty.

Kenton's early childhood was spent with her maternal grandmother, a strict taskmaster who reputedly had her granddaughter toilet trained by the time she was six months old and struck her if she did not sit straight.

[5] In her account of her relationship with her father, she relates that she challenged him about her experience in 1972, seven years before he died, when he was in London to record for the BBC: "He was a big man and he physically crumpled".

Susannah was conceived after a one-night stand with an old boyfriend, Barry Comden, who later married Doris Day,[9] leading to an estrangement from her father which lasted for some years.

[9] Kenton spent much of her life in the United Kingdom, moving to London after a short period living in Paris.

In 1995, Kenton was described as a "high priestess of New Age health and beauty: champion of every fad from chanting to ivy juice".

[8] In Journey to Freedom: 13 Quantum Leaps for the Soul (1999), she wrote about shamanism, which claims to be a means of communicating with the natural and spirit world.

[10] With Aaron, her youngest son, she began Cura Romana in 2008, which claims to be a natural method for weight loss.
