#4. Thatcher gave birth to twins
After marrying wealthy, divorced businessman Denis Thatcher in 1951, Margaret gave up her scientific career. “I just didn’t like staying in the laboratory that long,” she said in a 1987 television interview. “I wanted to have more direct work to do with people.” The couple had twins Mark and Carol in 1953, and the following year Thatcher became a barrister specializing in tax law.
