In 1980 the Principal commissioned Hugh Barty-King to write a book telling the history of the first 100 years of the Guildhall School of Music & Drama.  There are two references to Alfred Nieman:

In a section on the School when it moved from it's original home in John Carpenter Street to the Barbican Estate in 1977 he says,

“The Student Contemporary Music Society was the cradle of many distinguished performers and composers...  Its presiding genius, then as now, was Alfred Nieman, himself a composer and unique teacher, who had baffled or enlightened generations of students with the mysteries of Webern and Stockhausen almost before anyone had heard their music in this country.  Without him, it is doubtful if any Guildhall student in the 1960s would have left even knowing the music of Stravinsky.” (p130)

Talking of the Composition Course later on he says,

“One novel aspect of the course in 1980 was the improvisation sessions under Alfred Nieman.  Mr Nieman was still associated with the School after thirty-three years, and always kept a fresh open mind about the latest in contemporary music.  He undertook his role of agent provocateur with great relish, demolishing the routine and academic.”
