Jacob Matijevic

Jacob (Richard) Matijevic, also known as "Jake" Matijevic, (3 November 1947 – 20 August 2012) was an American NASA engineer of Croatian origin who worked on Mars Exploration Rovers. Dr. Matijevic was involved in developing the "Sojourner", "Spirit", "Opportunity" and "Curiosity" rovers. For his contributions to the rover projects, NASA named several landmarks on the planet Mars (including "Matijevic Hill" and "Jake Matijevic" rock) after him.

Dr. Matijevic was born and grew up in Chicago, Illinois and graduated from Mount Carmel High School. In 1969, he received a bachelor's degree in mathematics from the Illinois Institute of Technology, and, in 1973, earned a Ph.D. degree in mathematics from the University of Chicago under the supervision of Irving Kaplansky.

In 1981, Dr. Matijevic began working at the Jet Propulsion Laboratory (JPL) in Pasadena, California, as a control systems engineer. In 1986, he worked in the telerobotics field and later, in 1992, began work with the Mars "Sojourner" rover. This rover was delivered to Mars by the Pathfinder spacecraft in 1996.
