It was my pleasure to know Farouk Odeh over a period of twenty-four years. After meeting him at Yorktown Heights on a visit in 1968, I did not have occasion to meet him again until a joint IEEE-SIAM meeting in Boston in the Fall of 1982. In the interim, in a 1982 paper on the elastica, Michael Golomb and I referenced a related, beautiful paper of Oden ahd Tadjbakhsh [J. Math.Anal. appl. 18 (1967), 59-74]. After the Boston reacquaintance, Farouk and I kept in regular contact during the remaining nine and one-half years of his life. This included the exchange of visits between Evanston and Yorktown Heights, the exchange of ideas and papers, and, most importantly, the exchange of friendship. At a minisymposium which I organized at the 1986 SIAM annual meeting, Farouk presented what was then a novel model for mathematicians working in semiconductor device simulation and analysis, the hydrodynamic model. This was to have a profound impact on the work of myself and many others, including Carl Gardner. The paper of Rudan and Odeh was our starting point. The paper of Gnudi, Odeh, and Rudan was a rich source of information, motivating much further work. It is sad to know that his explicit presence no longer graces our intellectual stage ; the impact of his ideas and many interactions will endure for a very long time to come.
