Tomizo Yoshida (吉田 富三, Yoshida Tomizō, 1903–1973) was a prominent Japanese

pathologist, famous for discovering the Yoshida sarcoma. In addition, he is known for demonstrating the chemical-induced hepatocarcinogenesis in rats with his mentor Takaoki Sasaki
.

Yoshida received the

Robert Koch Gold Medal
(1963).

Contribution

In the 1930s Yoshida and Sasaki showed the induction of

Azo dyes.[2]

In 1943, Yoshida found a

cell line, so-called Yoshida Sarcoma,[3] and experimentally proved that cancer is generated from cancer cells. His findings opened the way of cancer research in terms of cells, and developed biomedical research on chemotherapy.[4]

Biography

Yoshida was born in

Imperial University of Tokyo in 1927.[5] He was an assistant professor of pathology at the same institution from 1927 to 1929.[5] In 1929 he moved to the Sasaki Institute to work on chemical-induced carcinogenesis with Takaoki Sasaki, before he went to Germany to study pathology in 1935.[5]

After returning to his homeland, Yoshida served as a professor of pathology at

Faculty of Medicine, University of Tokyo in 1952, where he became a dean in 1958.[5] In addition, he became a director at the Sasaki Institute in 1953 and at the Cancer Institute, Japanese Foundation for Cancer Research in 1963.[5]

Yoshida died in 1973 at the age of 70.
