Thomas was manager of the computer laboratory of The School of Mathematics from 1985 until 1997.
With his inception into the job, he brought the laboratory into a new era - for example, he set up a local communications network and exchanged the VAX computer with a group of new SUN servers and work stations with high graphic capability. At a later date, he was one of the main motivators of the idea of transferring the data communications of the university from its limited bitnet technology to an internet infrastructure.
Bringing the laboratory to the forefront of technology for which an annual equipment program had to be built, was turned by Thomas into a masterpiece with maximum utilization of the resources which were available to him. All this was done amid great concern for both students and staff and amid creation of a novel environment designed to encourage independence and new ideas. Amongst other things, he initiated the establishment of the general purpose laboratory and dealt with all the matters necessary in order to set it up including the internal plan. In his last years he taught advanced courses in the computer science department of the School of Mathematics.
Simultaneously with his management of the laboratory, Thomas also occupied himself with theoretical mathematics, literature (mainly Shakespeare) and learning Greek. He took photographs, drew, wrote poetry in English, Czech and German and translated poetry from German to English. He also had a deep interest in philosophy and classical music.
Thomas was the living spirit in the laboratory and in The School of Mathematics. He succeeded in creating exceptional relationships with everyone around him due to his being a multi-disciplinarian, renaissance and original man with a unique presence, a warm and drawing personality, an outstanding sense of humor and the radiation of a forceful vitality .
