This is a biography of William 'Guillermo' Gibbs (1790–1875), an Anglo-Spanish businessman and philanthropist. Born in Madrid and raised between Spain and England, he joined the family firm Antony Gibbs & Sons, helping to expand its operations across Spanish America and Asia. He played a pivotal role in establishing the family's fortune based on a diversed portolio of trading activities - i.e. never relying on a single commodity, although quina (Cinchona) was key in opening the gates to securing an export contract of guano with the Peruvian government in the 1840s. That arrangement both contributed to transforming Western agriculture and left him with the reputation of having made his fortune from 'the excrement of foreign birds'. From the 1850s, Gibbs turned to philanthropy, funding churches aligned with the Oxford Movement, restoring cathedrals, and supporting social housing. His Somerset estate, Tyntesfield, purchased in 1843 and refurbished in neo-Gothic style, reflected his religious convictions and Hispanic background. Gibbs retired in 1858 but remained the firm’s figurehead until his death. Tyntesfield stayed in the family until 2001, when it was saved by public campaign and acquired by the National Trust.
