She was born to Charles Bosch Reitz (1829–1879), a member of the Provincial Council of North Holland, and Sara Maria de Balbiaan (1839–1920).
After displaying artistic inclinations, she received sculpture lessons from Georgine Schwartze and Bart van Hove.
[2] In 1898, she created one of her few large sculptures, depicting a female stone carrier, pushing a wheelbarrow; made specifically for display at the Nationale Tentoonstelling van Vrouwenarbeid.
Throughout her twenties and early thirties, she held numerous exhibits, notably at the Tentoonstelling van Levende Meesters [nl] and the Exposition Universelle (1900).
