Bernhard Karlgren
Klas Bernhard Johannes Karlgren (traditional Chinese: 高本漢; simplified Chinese: 高本汉; pinyin: Gāo Běnhàn, 15 October 1889 – 20 October 1978) was a Swedish sinologist and linguist who pioneered the study of Chinese historical phonology using modern comparative methods. In the early 1900s, Karlgren conducted large surveys of a number of Chinese dialects and studied historical information on rhyming in ancient Chinese poetry, then used them to create the first ever complete reconstructions of what is now called Middle Chinese and Old Chinese.
