George Combe worked briefly as a lawyer and a brewer before devoting his career to the promotion of phrenology; a pseudo-science which explored the relation between the shape of someone?s skull and their personality, intelligence and economic prospects. Although even at the time many people doubted the `scientific? evidence for such assumptions, Combe believed that phrenology was `the greatest and most important discovery ever communicated to mankind?. He published widely on the subject, and his book `The Constitution of Man? became something of a bestseller. In 1833 he married Cecilia Siddons, but only after subjecting both himself and his future bride to a phrenological examination in order to find out if the match was a suitable one.
