American astronaut Alan Bean, who walked on the moon in 1969 during the Apollo 12 mission and commanded a crew on the Skylab space station in 1973 before giving up his career to become a full-time painter, died in Houston on Saturday, officials said.

Bean, 86, a former U.S. Navy test pilot who became one of only 12 people ever to set foot on the moon, died at Houston Methodist Hospital, his family said in a statement released by the National Aeronautics and Space Administration (NASA). He had fallen ill two weeks ago while traveling in Fort Wayne, Indiana.

"Alan was the strongest and kindest man I ever knew. He was the love of my life and I miss him dearly," said Leslie Bean, Bean's wife of 40 years, in a statement. "A native Texan, Alan died peacefully in Houston surrounded by those who loved him."
