At a dinner following her formal adoption as Conservative candidate for Dartford in February 1949 she met divorcé Denis Thatcher, a successful and wealthy businessman, who drove her to her Essex train. After their first meeting she described him to Muriel as "not a very attractive creature – very reserved but quite nice". In preparation for the election Roberts moved to Dartford, where she supported herself by working as a research chemist for J. Lyons and Co. in Hammersmith, part of a team developing emulsifiers for ice cream. She married at Wesley's Chapel and her children were baptised there, but she and her husband began attending Church of England services and would later convert to Anglicanism.
