# Ami Harten

**Amiram Harten** (1946 – 1994) was an American/Israeli applied mathematician. Harten made fundamental contribution to the development of high-resolution schemes for the solution of hyperbolic partial differential equations. Among other contributions, he developed the total variation diminishing scheme, which gives an oscillation free solution for flow with shocks.[2]

In 1980s, Harten along with Björn Engquist, Stanley Osher, and Sukumar R. Chakravarthy developed the essentially non-oscillatory (ENO) schemes. The article on ENO, titled, *Uniformly High Order Accurate Essentially Non-oscillatory Schemes, III* was published in Journal of Computational Physics, in 1987 [3]
and is one of the most cited papers in the field of scientific computing. It was republished in 1997 in the same journal.[4] Harten is listed as an ISI highly cited researcher.[5]

In 1990 Harten gave a talk on "Recent developments in shock-capturing schemes" at the International Congress of Mathematicians in Kyoto.[6]
