After the war, funded by the GI Bill, Huebler earned his bachelor's and master's degrees at the University of Michigan, and later went on to study at the Académie Julian in Paris.

In 1969, he participated, with Joseph Kosuth, Robert Barry and Lawrence Weiner, in a landmark exhibition of conceptual art curated by Seth Siegelaub.

Huebler subsequently started producing works in numerous media often involving documentary photography, maps and text to explore social environments and the effect of passing time on objects.

In the 1980s and '90s, Huebler began incorporating painting into his conceptual art pieces, creating a persona he called "the Great Corrector," who took works by masters like Picasso, Matisse, Bruegel and Hieronymus Bosch and attempted to "make them better."

For his "Buried Treasure" series, incorporating text about the unscrupulous dealer, Huebler paints fake Monets, Van Goghs, Gauguins and a De Chirico.
