Zhang Daqian or Chang Dai-chien (Chinese: 張大千 or 张大千; 1899 - 1983) was one of the best-known and most prodigious Chinese artists of the twentieth century. Originally known as a guohua (traditionalist) painter, by the 1960s he was also renowned as a modern impressionist and expressionist painter. In addition, he is regarded as one of the most gifted master forgers of the twentieth century.
A meeting between Zhang and Picasso in Nice, France in 1956 was viewed as a summit between the preeminent masters of Eastern and Western art. The two men exchanged paintings at this meeting. Zhang's forgeries have been purchased as original paintings by several major art museums in the United States, including the Museum of Fine Arts, Boston. Viewing the Waterfall, 1963, was sold for price of HK$64,225,000 in 2018 at Christie’s Hong Kong.
