LOS ANGELES: Agnes Nixon, the creative force behind the enduring TV soap operas One Life to Live and All My Children, died Wednesday. She was 93.

Nixon died at a Haverford, Pa., physical rehabilitation facility close to her Rosemont home, said her son, Bob Nixon. She had checked in to gain strength for a planned book tour, he said.

Nixon had just finished writing her memoir, My Life to Live, on Sunday, a week before it was due to publisher Penguin Random House, her son said.

The cause of death was not immediately known, he said.

All My Children had aired for nearly 41 years, while One Life to Live had made it to 44 seasons. Both were set in fictional Philadelphia-area towns.

Her memoir is scheduled to be released in early 2017.
