Daughter of a British obstetrician and his Dutch wife, Jane was born in Hillingdon , England and raised in Wimbledon . She began training in dance at an early age, and was just 13 when she made her professional debut with the London Festival Ballet. That same year, she entered the Arts Educational Trust for dance, music and theatre training and danced with the visiting Kirov Ballet at Covent Garden .

Seymour played roles in a range of classical plays and performed in radio dramas. But it was as Winston Churchill's first love, Pamela Powden, in the Carl Foreman motion picture, “Young Winston,” that Jane attracted the attention of top producers. Her first television series was the BBC-TV project, “The Onedin Line,” and this led to her winning the starring role of Solitaire in one of the most popular James Bond films, “Live and Let Die.” This attracted Hollywood interest, but Seymour opted to return to the boards of English repertory theatres to tackle such classic leading ladies as Shakespeare's Ophelia and Lady Macbeth, and Ibsen's Nora in “A Doll House.” On the Broadway stage, she originated the role of Constanza Weber, wife of Mozart in the Broadway hit “Amadeus.” Seymour has also emerged as a significant producer of distinguished projects. Through Catfish Productions, she and her husband, director James Keach, have produced, starred in and directed such programs as “Sunstroke,” “A Passion for Justice,” “Praying Mantis.” “The Absolute Truth,” “Enslavement: The Fanny Kemble Story,” “Murder in the Mirror,” “Dr. Quinn, The Movie,” “A Marriage of Convenience” and “Blackout.” In addition, Seymour recently starred in “Yesterday's Children.” Seymour 's success as an author has been exemplified by the success of her non-fiction novel entitled “Two at a Time: A Journey through Twin Pregnancy and Birth.” In May 2003, she released another non-fiction work titled “Remarkable Changes.” The book chronicled the stories of several individuals, including Seymour herself, as they overcame adversities. In addition, Seymour and Keach have co-authored a series of exceedingly successful children's books entitled “This One and That One,” inspired by their delightfully altered lives since the actress gave birth to twins in late 1995. Published by Putnam, the books transpose the Keach household into a family of cats whose lives are constantly energized by the antics of their toddler kitty twins, This One and That One. In 2003 Saks Inc. announced an exclusive agreement with the celebrated actress, artist and author to develop a branded line of Jane Seymour lifestyle home products and children's apparel in its Saks Department Store Group stores. Seymour is the extremely hands-on mom of twins John and Kristopher, Sean and Kat ie, her stepdaughter Jenni and stepson Kalen. Seymour and Keach reside in Malibu , and she owns St. Catherine's Court, a 15th century historic manor house near Bath , England , which she is dedicated to preserving. Actively involved in numerous charitable causes, Seymour is a member of the American Red Cross National Celebrity Cabinet and works for Childhelp USA , a national organization dedicated to the research, treatment and prevention of child abuse, as International Ambassador. The organization's “Woman of the World” award is one of many honors she has won for her social and charitable achievements. Seymour is also the Honorary Chairperson for City Hearts, an organization that enriches the lives of abused children, inner-city children, and disadvantaged youths, by teaching the performing arts, including painting, dancing and acting. She is also an ambassador for children's issues for the film world's charitable arm, Entertainment Industries Foundation/Permanent Charities. Inspired by a recent trip to Africa with the American Red Cross, Seymour and Keach have partnered yet again to start the J&J Foundation to benefit children in need. Keach captured the entire eye-opening experience on film for an award-winning documentary “Disease of the Wind,” which won the Lionel Rogosin Documentary Award and Audience Award Best Documentary at the Dallas Film Festival. The film follows the story of Jane Seymour and eight inner-city children from Los Angeles traveling with the Red Cross to Kenya to participate in the vaccination of 13 million children against measles, which kills over one million children a year. Seymour 's talents as a fine artist led to the production of a series of greeting cards sold on her website to support her charities. One of her watercolors was featured on a special “Private Issue” Discover Card and it raised $25,000 for the Make-A-Wish Foundation at a charity auction at the Guggenheim Museum , while a subsequent painting sold for an additional $20,000. She was also asked to design a special edition bottle for Korbel Champagne , and a silk scarf for Escada, another charitable endeavor. She recently designed sets and costumes for the Houston Ballet's “Five Poems” to celebrate the 25 th anniversary of artistic director Ben Stevenson.
