Professor Pieter Zeeman (1865-1943). Archive of more than 200 invoices and receipts,
ca. 1895-1920, a highly diverse collection mostly addressed to his wife J.E. Zeeman-Lebret (1873-1962), mostly at address Stadhouderskade 158 Amsterdam, but also from the time the family lived in Leiden at Plantsoen (number 75).
A very interesting glimpse into the personal pattern of expenditure of the Dutch physicist and Nobel laureate Pieter Zeeman. On him, see: https://tinyurl.com/lxdnsh9.
