Moreover, William organized a choir, numerous plays and concerts, and taught classes in the Assyrian language and literature.
In Tehran he also began working on his lifelong ambition, writing the Assyrian Epic of “Kateeny the Great” in verse. He completed the first volume of the epic and also wrote an Assyrian book of verse for children titled “Rameena the Naughty”. Both books were published in 1961 by the Assyrian Youth and Cultural Society of Tehran. William’s first book of songs, “The Rays of Light” was also published at this time.
William immigrated to the United States in 1952 and settled in Chicago. There he continued to teach the Assyrian language, wrote music, organized plays and choirs, wrote articles for the Assyrian magazines and gave lectures at various functions. He was the editor of the periodical “Mhadyana” in the 1960’s. In 1970, his musical piece, “Juvenile Suite”, won the Beblis award. William published the second volume of “Kateeny the Great”, his music collection “William Daniel’s Creations”, “Assyrians of Today, Their Problems and a Solution”, and the bilingual play “Kismat” in Chicago.
In 1979, William came to San Jose, California. During his years in San Jose, William served as the Editor of the Assyrian Star magazine, wrote numerous articles, poems, and musical pieces. In 1983, he published the third and last volume of the epic of “Kateeny the Great”, immortalizing it in a compilation of over 7,000 verses, and narrated Volume I and II of the Epic on tape.
