 Hyman's role was to facilitate communication with the large and linguistically diverse client base of this pharmacy.During this entire period, Hyman pursued an avocation as a composer, primarily of liturgical music, and by 1975 had completed his major work, a complete musical score for the Haggadah of Pesach (Passover), which was eventually published in 1999.A second major liturgical work based on the Sabbath prayer service is due for publication in 2009.
