On his father's death in 1836, Anthony became a partner in the bank. Anthony's eldest brother
Lionel de Rothschild worked at the bank but in time became more and more involved in politics. With younger brother
Nathaniel settling permanently in Paris and acquiring the
Château Brane Mouton vineyard, and youngest brother
Mayer Amschel showing little interest in banking, a good portion of the responsibility for running the family's investment house fell on Anthony's shoulders. Working with brother Lionel and his cousin
James in Paris, Anthony was a key figure in the 1845 creation and management of the
Chemin de Fer du Nord, the family's rail transport business in France. Anthony Rothschild's involvement with the financing of European railways was extensive and included the
Chemins de fer de Paris à Lyon et à la Méditerranée, the Imperial Lombardo Venetian and Central Italian Railway Company of which brother Lionel was a director as well as funding railroad construction in
Brazil. In the 1840s he was involved with their investment in an ironworks in
Mexico that supplied product for the building of that country's railway system. In addition, he was part of the 1852 negotiations for the lease whereby the Rothschilds took over the running of the
Royal Mint Refinery in London and took charge of overseeing the operation. ==Private life==
