Agnes Nixon

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 physical rehabilitation facility 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.”

Nixon created, wrote and produced the long-running ABC daytime serials, which were canceled in 2011 as the network bowed to the reality that soap operas had faded as a daytime TV force.

“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.
