Sir Samuel Morton Peto, 1st Baronet was an English entrepreneur, civil engineer and railway developer, and, for more than 20 years, a Member of Parliament (MP). A partner in the firm of Grissell and Peto, he managed construction firms that built many of London's major buildings and monuments, including the Reform Club, The Lyceum Theatre, Nelson's Column and the replacement Houses of Parliament - commissions which brought him great wealth. The scale of his operations, and that of the workforces needed to undertake them, made him the world's largest employer.

The Reform Club is a private members' club, owned and controlled by its members, on the south side of Pall Mall in central London, England. As with all of London's original gentlemen's clubs, it had an all-male membership for decades, but it was one of the first all-male clubs to change its rules to include the admission of women on equal terms in 1981. Since its foundation in 1836, the Reform Club has been the traditional home for those committed to progressive political ideas, with its membership initially consisting of Radicals and Whigs. However, it is no longer associated with any particular political party, and it now serves a purely social function.
