Yan Fu was a Chinese scholar and translator, most famous for introducing western ideas, including Darwin's "natural selection", to China in the late 19th century.

　　On January 8, 1854, Yan Fu was born in what is modern day Fuzhou, Fujian Province to a respectable scholar-gentry family in the trade of Chinese medicine. In his early years, Yan Fu's father greatly encouraged Yan Fu to obtain a high education and prepare for the Imperial examination. However, the death of his father in 1866 caused an abrupt change to these plans. A year later, Yan Fu entered the Fujian Arsenal Academy (福州船政學堂) in Fuzhou, a Western school where he studied a variety of subjects including English, arithmetic, geometry, algebra, trigonometry, physics, chemistry, astrology and navigation. This was a turning point in young Yan Fu's life as he was able to experience first-hand contact with Western science, thus inspiring the enthusiasm that carried him through the rest of his career.

　　After graduating with high honors in 1871, Yan Fu went on to spend the next five years at sea. He first served aboard the training ship Jianwei (建威) and later on the battle cruiser Yangwu (陽武). In 1877–79 he studied at the Royal Naval College, Greenwich, England. During his years there, he became acquainted with China's first ambassador Guo Songtao, and despite their age difference and status gap developed a strong friendship. Benjamin Schwartz mentions in his biography that "they often spent whole days and nights discussing differences and similarities in Chinese and Western thought and political institutions".

　　His return to China, however, did not bring him the immediate success he was hoping for. Though he was unable to pass the Imperial Civil Service Examination, he was able to obtain a teaching position at the Fujian Arsenal Academy and then Beiyang Naval Officers' School (北洋水師學堂) at Tianjin.

　　It was not until after the Chinese defeat in the First Sino-Japanese War (1894–95, fought for control of Korea) that Yan Fu became famous. He is celebrated for his translations, including Thomas Huxley's Evolution and Ethics, Adam Smith's The Wealth of Nations, John Stuart Mill's On Liberty and Herbert Spencer's Study of Sociology. Yan critiqued the ideas of Darwin and others, offering his own interpretations. The ideas of "natural selection" and "survival of the fittest" were introduced to Chinese readers through Huxley's work. The former idea was famously rendered by Yan Fu into Chinese as tiānzé (天擇).

　　Yan Fu served as an editor of the newspaper Guowen Bao. He became politically active, and in 1895, he was involved in the Gongche Shangshu movement, which opposed the Treaty of Shimonoseki ending the First Sino-Japanese War. In 1909 he was given an honorary Jinshi degree. In 1912 he became the first principal of National Peking University (now Peking University).

　　He became a royalist and conservative who supported Yuan Shikai (袁世凱) and Zhang Xun (張勛) to proclaim themselves emperor in his later life. He also participated the foundation of Chouanhui (籌安會), an organization which supported restoring monarchy and he looked down upon "New Literature Revolutionaries" .

　　On October 27, 1921, after returning to his home in Fuzhou only a year earlier to recuperate from his recurring asthma, Yan Fu died at the age of 67.
