George Palmer Putnam (September 7, 1887 – January 4, 1950) was an American publisher, author and explorer. Known for his marriage to (and being the widower of) Amelia Earhart, he had also achieved fame as one of the most successful promoters in the United States during the 1930s.
Putnam lived longer than his wife.
It says he was a widower so his wife died while he still lived. The system didn't find the same words in the text as the sentence.
