Robert Larue (Bob) Miller

Bob Miller’s creative practice was defined by an "unhardening of the categories," as he used to say—a refusal to accept formal categories of study such as science, art, math, or engineering. Instead, he called himself a "natural philosopher" and made a practice of wandering, musing, hypothesizing, and collaborating, building new questions on the backs of the old ones.

Miller was born in Niagara Falls and studied at Hiram College in Ohio. After working for a short time with the army at the White Sands Proving Ground in New Mexico, he began computer programming at IBM, later joining the Merchant Marines and eventually settling in San Francisco. Fascinated by optics, he began to construct artful experiments using natural light and prisms in his small apartment.

During a visit from Exploratorium Founding Director Frank Oppenheimer in 1970, Miller was offered a job at the museum that lasted nearly 20 years. His early investigations gave way to the creation of the museum’s Artist-in-Residence program, and he played several roles on staff, including exhibit developer, teacher, and assistant director. He designed and built a number of beloved and iconic exhibits at the museum that focus on light, color, shadow, and perception including: Sun Painting (1970); Sophisticated Shadows (1980); Cheshire Cat (1978); Everyone Is You and Me (1980); and Aurora (1976).

But perhaps his most enduring contribution was the most ephemeral: Miller’s Light Walk was a pedagogical walking tour that lasted from an hour to an entire day, illuminating principles of light using simple yet ingenious props and tools. Those lucky enough to experience a Walk never see the world in quite the same way.

Here’s an exhibit where watching is at least half the fun. You can create any number of gravity-defying illusions that will amaze you and your friends: Levitate, fly, swim though the air, grow limbs (and dissolve them), crawl straight up the wall like a lizard—the sky’s the limit.

If you think shadows are a straightforward business, prepare for a surprise—actually, a whole bunch of surprises. Combining various light sources in various ways, you’ll quickly discover that there’s nothing simple about a simple shadow.
