Helmreich was a distinguished professor at the City University of New York,[4] who specialized in race and ethnic relations, religion, immigration, risk behavior, the sociology of New York City, urban sociology, consumer behavior, and market research.
Helmreich wrote about his early years in a book he named "Wake Up, Wake Up, to Do the Work of the Creator" (a phrase, spoken in Yiddish, by those who went house-to-house to awaken worshippers for daily prayer).[11]
When asked about recordings of "many of the famous roshei Yeshiva of yesteryear" whom he interviewed, "Do you still have the recordings?" he replied "At one time I thought I did, but it seems that all I have are the transcripts." These he donated to his alma mater,[12]Yeshiva University.[13][14][15]

The World of the Yeshiva
Helmreich revised his 1982 The World of the Yeshiva 18 years later[1] by comparing sociological changes "among the strictly Orthodox" since his 1980 research. Two areas about the new edition highlighted by The New York Times are the doubling in those doing full-time "collegiate and graduate"-level religious studies and population growth.
