Born in Luxembourg, Roeder moved Richmond, CA in 1909 with his wife and children. Roeder worked as a pipe fitter for many years and then as a gardener for the local High School.
In his downtime, Roeder taught himself to paint and sculpt using found materials and inexpensive paints.
The Traveling Observatory has all the elements of a complex Roeder; fantasy, mystery, humor and great trees. A man stands holding the reins of a horse-drawn carriage that then becomes a landscape of switchback trees and fences upon which two men with telescopes sit on a see-saw. At the top of this landscape are snowy white mountains with numerous moons or planets in the distant sky.
