Capturing the Light: Rosalie Heacock Thompson’s Plein Air Legacy

Plein air painting—French for “in the open air”—has long attracted artists seeking to capture nature as it unfolds. For Rosalie Heacock Thompson (1927–2022), plein air was more than a technique—it was a lifelong discipline. Whether perched on the edge of a canyon or nestled into a seaside bluff, she painted directly from life with reverence, clarity, and joy.

Painting in Place

Over eight decades, Rosalie created more than 450 works, many of them painted outdoors in the shifting light of Southern California and New Mexico. She was a founding member of the Plein Air Artists of the Santa Monica Mountains and Seashore, and her vibrant watercolors became part of the California plein air revival movement beginning in the 1980s.

Armed with stretched paper boards, a handmade paint box, and a deep sensitivity to natural rhythms, she completed full compositions in a single session. Her work is infused with ecological intimacy—recording birds in flight, seasonal wildflowers, or the way filtered sunlight dapples canyon trails.

A Sense of Community

Rosalie’s plein air practice was often communal. Alongside fellow artists, she hiked into remote locations, shared simple open-air meals, and celebrated the aesthetic in everyday moments. These plein air gatherings formed a creative ecosystem where ideas, techniques, and inspiration were exchanged.

Ongoing Inspiration

While her body of work spans from the 1940s through the early 2020s, Rosalie’s approach remained remarkably consistent: paint in nature, observe closely, and finish what the light allows. Even into her nineties, she painted with a steady hand, a sharp eye, and an open heart.
