Impossible was not a word for Daisy Kilsheimer Miller.

Whether it was ending world hunger, trying to save the environment, or beating cancer, Mrs. Miller was always confident she would win. And she believed it to her last breath.

Mrs. Miller, co-founder of Kids Ecology Corps and executive director of End World Hunger Inc., died Sunday at 55 after a long battle with breast cancer.

"She would never quit," said Leonard Solomon, her co-founder of Kids Ecology Corps. "We could not even talk to her about funeral arrangements. Three weeks ago she called me and said her doctor fired her because she had no chance. She wanted me to help her convince him to get back on board."

Born in Brazil in 1946, Mrs. Miller moved with her parents to Washington, D.C., when she was a year old. She attended Webster College and in 1969 married John Miller, who died of cancer two years later.

Soon after, she moved to Fort Lauderdale and became involved in causes such as the Hunger Project, a worldwide effort to end famine. The idea was to educate people in order to create the political will to enact reforms, Solomon said.

As an offshoot of that program, Mrs. Miller and Solomon founded End World Hunger Inc. Solomon said their target audience was those who could learn easier: children.

Part of that crusade was a transcontinental bicycle ride she undertook in 1981 with 31 other bikers to draw attention to their cause. The trek took them from Fort Lauderdale to San Francisco. They met thousands of people and received proclamations from 11 governors and then-President Jimmy Carter.

In 1994, she co-founded the Kids Ecology Corps, a program designed to teach young people about environmental causes. Solomon said the program has taught more than 25,000 students and works with Broward County Public Schools and Florida Atlantic University.

"She was on mission to try to make the world a better place ... ," Solomon said.
