Childhood, education and early career

Hans Reiser was born to Ramon Reiser[1] and Beverly Palmer[2] on December 19, 1963. He grew up in California and dropped out of his junior high school before he was 14, citing disagreements with the conventional schooling system. He was accepted at the University of California, Berkeley at the age of 15, which he attended off and on until he received a BA in Systematizing (an individualized major dealing with physics, math and related topics) in 1992, at the age of 28. [3] Reiser was also one of the founding members of the Open Computing Facility at UC Berkeley. Though preferring higher education, Reiser chose not to pursue a Ph.D., citing the same reasons he had dropped out of junior high school.[4] He was therefore unable to pursue a further career in academia and worked part to full time in the computer field while founding and building the California-based international software company Namesys Inc. Prior to founding Namesys, Reiser held positions at Synopsys, IBM Research, Premos and ARDC.
