Cao Chunan (Chinese: 曹楚南; pinyin: Cáo Chǔnán; August 15, 1930 – August 27, 2020) was a Chinese scientist who specialized in corrosion and electrochemistry. He was a member of the Jiusan Society.

## Biography

Cao was born in Changshu County (now Zhangjiagang), Jiangsu, on August 15, 1930. He had five brothers. He secondary studied at Liangfeng High School. In 1948, he was accepted to Tongji University, where he majored in chemistry. After graduation, he was assigned to the CAS Shanghai Branch, in 1952, becoming associate research fellow in 1979 and dean and research fellow in 1982. In 1987, he was transferred to the Institute of Metal Research. He became a professor at Zhejiang University in 1994. In 1999, he concurrently served as dean of College of Environment and Resources, Zhejiang University. He died of illness in Hangzhou, Zhejiang, on August 27, 2020.
