Thomas Peters, 1861 - 1947

Thomas Peters appears to have taken up microscopy and preparing slides after he retired from dental practice. He joined the Quekett Microscopical Club in 1938. His known slides have careful arrangements of select diatoms, radiolaria, and similar objects, and are precisely finished with simple black ringing (Figures 1 and 2).

Thomas Peters was born on November 8, 1861, in Leigh, Lancashire, England. He was the first child of Joseph and Lydia Peters. Joseph’s profession was listed as “joiner” (i.e. woodworker) on the 1871 census and on Thomas’ 1886 marriage record, although he diverted to working as a “grocer” at the time of the 1881 national census.
Thomas worked as a “teacher of music” in 1881, when he was 17 years old and living with his parents and siblings. For 15-20 years after that, he worked as a “letter press printer”. An 1895 director indicates that Peters operated his own printing and bookbinding business, working in the family house.
Thomas married Elizabeth Gerrard on July 13, 1886. They had four children, three boys and 1 girl. Son Gordon died when only four years old.
Around the turn of the century, Peters changed professions and became a dentist. While I located his wife and children in the 1901 census, at their home in Leigh, Thomas Peters was not at home and has not been identified elsewhere. Considering his career change at that time, he might have been undergoing dental training at another location.
A 1905 trade directory listed Thomas Peters under “artificial teeth manufacturers”. He was not, however, listed as a dentist, suggesting gradual steps into that profession. The 1911 census listed his profession as “dental surgery”, and the 1921 census has him as a “practitioner of dentistry”.
Wife Elizabeth died in 1936. The 1939 Registry of England and Wales shows Thomas and his unmarried daughter, Doris, living at 22 Railway Road, Leigh. Thomas was listed as “dentist, retired”, and Doris was an “elementary school teacher”.
Peters probably took up slide-making during his retirement. He joined the Quekett Microscopical Club on December 6, 1938. It being that the QMC is headquartered in London, Peters probably never attended a meeting in person but would have benefitted from articles in the Club's publications. He is not known to have written any publications on microscopy.
Thomas Peters died on September 5, 1947, at the age of eighty five.
