Herolt was the eldest daughter of the painters
Maria Sibylla Merian, and Johann Andreas Graff, and learned to paint from them along with her sister
Dorothea Maria Graff. Though she was born in Frankfurt, in 1670 the family moved to Nuremberg, where she was raised. Though Johann Graff joined his family later, in 1686 Merian left her husband and moved with her two daughters and her mother to a religious community of
Labadists in
Wieuwerd, Friesland. Johann Graff made various attempts at reconciliation but eventually returned to Germany. In 1691 the four women moved to
Amsterdam, where they set up a studio painting flowers and botanical subjects, continuing Merian's work on "The Caterpillar Book". Johanna married the merchant Jacob Hendrik Herolt, also an ex-Labadist, on 28 June 1692. They had two children and Johanna began to take on her own commissions, working for
Agnes Block and the
Amsterdam Hortus like her mother. Johanna moved with her husband to
Surinam in 1711 where she died sometime after 1723. == Collaborations with Merian ==
