This duo-biography features Sir Robert Hadfield (1858-1940) – the renowned Sheffield alloy steelmaker – and his American wife, Frances ‘Bunnie’ Wickersham (1862-1949). Their wealthy lifestyle spanned Sheffield, London, the USA, the French Riviera, and Wimereux (near Boulogne), where Bunnie Hadfield organized a private hospital during the First World War. Based upon the author’s extensive archival research, this duo-biography portrays two contrasting individuals, whose transatlantic marriage was sometime fraught but survived at a time of great social and economic upheaval.
