I first met József at Oberwolfach in 1984, having been in correspondence since early 1983. I had arranged for him to spend the academic year 1984-85 at Imperial College London with support from the Science Research Council. Thus we began a longstanding collaboration in the theory of irregularities of point distribution.

József returned to Imperial College London for another two months in 1989, and visited me in Sydney twice, in 1993 and 1995. I visited him in Budapest in 1986 and 1987, and many times at Rutgers University since he moved there permanently in 1990.

Despite being a very fine mathematician, József prefers to play tennis instead. Mathematics can be done if there is any spare time.
