Russell William Porter (1871-1949) was, at times, an arctic explorer, astronomer, telescope engineer, professor of architecture, painter and technical illustrator.
In 1906, Porter joined an expedition to Alaska led by Frederick Cook. While Porter explored and surveyed the surrounding region, Cook and one other explorer set off to climb Denali, North America’s tallest mountain (aka Mount McKinley; 6,000m or 20,000 feet). Cook eventually returned, claiming success, and Porter became the first of many skeptics: Cook’s ascent was soon shown to have been falsified; he had actually climbed and photographed a much smaller nearby mountain now evocatively named “Fake Peak”.
Porter is best remembered for designing and hand-crafting many telescopes and observatories, including the initial sketches for the Griffith Observatory in the Hollywood hills, and contributions to the 200-inch Hale Telescope at Mount Palomar.
