Geoffrey Bowman was a printmaker specializing in lithography and intaglio printmaking techniques. In 1964 he joined the art faculty at San Jose State University and moved to San Jose and became a full professor in 1973. Geoffrey taught at SJSU for twenty-nine years. After retiring from teaching in 1994 Geoffrey turned to painting as his primary medium of expression. Although there was a media shift he continued to focus on one subject: the consistency of change. This he accomplished in part with combinations of paint and an assortment of reflective materials such as metallic flake and leaves, glass beads, and light-refracting pigments.
