The man who first calculated Everest's height never got his name on the mountain

In 1852, mathematician Radhanath Sikdar, working as a 'computer' for the Great Trigonometric Survey of India, calculated from trigonometric readings that a peak then known only as 'Peak XV' was the highest point on Earth. His figure, 29,002 feet, was remarkably close to today's accepted height — but the mountain was named after his former boss, Sir George Everest, instead.
