Confectioner Guglielmo Alexis [William Alexis] Jarrin was born in Colorno, near Parma, on 25 March 1784. He was probably of French descent (his early years coincided with the French occupation of northern Italy). He worked in Paris early in his career, but came to London in 1817. By 1819 he was employed as confectioner and ornament maker for James Gunter’s, confectioners, in Berkeley Square. In 1820 Jarrin published The Italian Confectioner. Written when confectionery production was on the point of being industrialised, the book represented the high point of artisan skills (it was reprinted at least ten times). By 1822 Jarrin had established his own shop at no. 123 New Bond Street and his clientele included a number of prominent persons. After a period of business expansion, Jarrin became insolvent and was declared bankrupt in November 1828. He was allowed to continue trading and for a short time he held premises in Tichbourne Street, but appears to have ceased work by 1836. He died in May 1848 at his home at no. 22 Cambridge Street, Hyde Park.
