"Marion Frieswyk embodies the diligence, determination, and innovative spirit that we value at CIA. Looking back over her career, Marion was a true pioneer.

She was the first woman in the Map Division’s Cartography Section, helped to develop a unique system of map production, and produced customized maps and 3D topographic models during WWII.

After OSS dissolved in 1945, she remained as part of the core group of cartographers who stayed with the unit, working in CIA’s Cartography Division until 1958.

Marion recognized early on that geography is deeply relevant to intelligence work, enhancing the Agency’s ability to visualize and tell stories that resonate with those we serve.

Her passion and spirit represent timeless qualities that define the Cartography Center to this day."
