Anna van Gelder was a sea captain’s wife in the 17th century. As was customary for women in her position, she was responsible for the bookkeeping, financial monitoring and provisioning for the ships under the command of her husband, Admiral Michiel de Ruyter.

With crews running into the hundreds, provisioning ships was a very exacting task. It is known that De Ruyters’ sailors received ‘generous portions’, which we can take to mean Van Gelder ran a solid procurement system. She also managed the booty revenue, sold residual goods and ensured that the sailors’ wives received their monthly allowance. Although Van Gelder was a wealthy and successful businesswoman, she was known for her frugal lifestyle: she did her own laundry and shopped at the market.
