<strong>TUG</strong>boat, <strong>Volume</strong> <strong>30</strong> (2009), No. 2 159 Pr<strong>of</strong>ile <strong>of</strong> Eitan Gurari (1947–2009) Eitan Gurari died unexpectedly on June 22, 2009. <strong>The</strong> <strong>TEX</strong> community mourns <strong>the</strong> loss <strong>of</strong> this important contributor. Eitan Gurari was born in March 1947 in Haifa, Israel, and grew up in Tivon, a small town near Haifa. He met his wife, Shaula, who was born and raised in Haifa, atadance. <strong>The</strong>yhadfivechildren: Adaughter Inbal, sons Itai and Erez, and twin daughters Netta and Danna. Eitan’s son, Itai, says, “My fa<strong>the</strong>r’s sole hobbies were his work and family. He enjoyed both immensely. Also, in recent years he and my mo<strong>the</strong>r began traveling a lot.” <strong>The</strong> children had all grown to adulthood at <strong>the</strong> time <strong>of</strong> Eitan’s death. Eitan’s 1989 book, An Introduction to <strong>the</strong> <strong>The</strong>ory <strong>of</strong> Computation, was dedicated, To Shaula, Inbal, Itai, Erez, Netta, and Danna. Eitan was educated at Technion–Israel Institute <strong>of</strong> Technology where, in 1971, he received a Bachelor <strong>of</strong> Science degree in physics. He continued his studies <strong>the</strong>re, but changed his focus to computer science, receiving a Masters degree in 1974. At that point he, his wife, and <strong>the</strong>ir <strong>the</strong>n only child, a daughter, moved to <strong>the</strong> United States where Eitan studied at <strong>the</strong> University <strong>of</strong> Minnesota, which granted him a PhD degree in computer science in 1978. Eitan’s faculty advisor at <strong>the</strong> University <strong>of</strong> Minnesota was Oscar Ibarra. After graduation from <strong>the</strong> University <strong>of</strong> Minnesota, Eitan moved to <strong>the</strong> University <strong>of</strong> Wisconsin– Milwaukee, where until 1980 he was an assistant pr<strong>of</strong>essor in <strong>the</strong> Department <strong>of</strong> Electrical Engineering and Computer Science. He next moved to <strong>the</strong> State University <strong>of</strong> New York at Buffalo, Department <strong>of</strong> Computer Science, where he served as an assistant pr<strong>of</strong>essor until 1982. In 1982, Eitan moved to <strong>the</strong> Ohio State University, where he was an associate pr<strong>of</strong>essor teaching computer science and doing research until his death. At Ohio State, Eitan taught a wide variety <strong>of</strong> courses, suggesting that he pitched in to teach whatever needed teaching and that he used <strong>the</strong> need to teach a course in a new area as a way <strong>of</strong> broadening his own knowledge. His web site at <strong>the</strong> time <strong>of</strong> his death listed <strong>the</strong> following courses that he had taught (we don’t know if this is a complete list): Introduction to Computer Graphics, 1993; Introduction to Computer Networks, 1998; Introduction to Data Structures, 1999; Introduction to Automata and Formal Languages, 1999; Introduction to Programming with Java, 2003; Advanced Technologies with Java, 2004; Programming Challenges, 2004; XML Technologies, 2005; Compiler Design and Implementation, 2008; Introduction to Programming with C ++, 2008; Data Structures for Information Systems, 2008; Introduction to Database Systems, 2009. Early in his career, Eitan’s interest was in <strong>the</strong> <strong>the</strong>ory <strong>of</strong> computation, and between 1978 and 1987 he had 18 papers in this field published in refereed journals, many <strong>of</strong> <strong>the</strong>m co-authored with Oscar Ibarra. Two typical titles are “Two-Way Counter Machines and Diophantine Equations” and “Some Decision Problems Concerning Sequential Transducers and Checking Automata”. During this period Eitan also had six papers published in conference or symposium proceedings. <strong>The</strong> culmination <strong>of</strong> this work appears to have been his already mentioned 1989 book on <strong>the</strong> <strong>the</strong>ory <strong>of</strong> computation. Eitan’s obituary notice on <strong>the</strong> website <strong>of</strong> <strong>the</strong> Computer Science and Engineering Department <strong>of</strong> Ohio State University said <strong>the</strong> following: Dr. Gurari started his career as a <strong>the</strong>oretician. He made fundamental contributions to automata and complexity <strong>the</strong>ory. His textbook, An Introduction to <strong>the</strong> <strong>The</strong>ory <strong>of</strong> Computation, was highly praised, and he published frequently in JACM, SIAM Computing, ACM STOC, and IEEE FOCS. <strong>The</strong> obituary notice continued, After joining OSU, Gurari switched his research focus, starting to build s<strong>of</strong>tware systems. We can see this transition from his writings and presentations in <strong>the</strong> succeeding years. 1991 “A WYSIWYG Literate Programming System” (Preliminary Report), with J.
