fifty one". Erysipelas is an acute infection of the skin and underlying fat tissues, usually caused by the streptococcus bacteria. Two of his sons, Charles Foster, born 1859, and Herbert Cassin, born 1863, in Clapham, Surrey, followed their father's footsteps into the wholesale drug trade, Herbert remaining on the board of directors into the 20th century. The eldest son, William Valentine Jr., born 1854, listed his occupation as "gentleman", while the youngest son, Sydney Faulconer, became a physician and surgeon. 1892: Charles Booth interview In 1892 as part of a survey into life and labour in London, the social researcher Charles Booth interviewed Charles Umney. The original record is in the archives of the British Library of Political and Economic Science: Park Street With an increasingly acute accommodation shortage at the Southwark Street premises, the drug laboratories and soap factory were moved north to 66-76 Park Street, Southwark in 1899. The factory was enlarged in 1920. During the 1930s the company bought the old business of Dakin Brothers in Middlesex Street. In 1942, additional factory premises were built at 66 Park Street and in 1950 a new additional warehouse was built in Southwark Street. The total floor space was by then two and one third acres.

The original roofline of Nos. 44 and 46, up to the Victorian cornice, survives, but Nos. 48 and 50 boast an additional modern attic storey. For much of the 20th century, Wright, Layman & Umney occupied all these properties. Limited company In June 1899 Wright, Layman & Umney became a private limited company with a capital of £100,000 and Charles Umney as director. Charles maintained an active role in the business until 1905 and subsequently acted as chairman of the company. In due course, Charles'
