[1] Herts was born in New York City, attended Columbia University without graduating, and apprenticed under Bruce Price.
He studied architecture in Europe at the École nationale supérieure des Beaux-Arts in Paris and at the Universities of Rome and Heidelberg.
Herts perfected the cantilevered arch construction that enabled theater architects to support balconies without the use of columns.
Herts continued in business with assistant Herbert J. Krapp and produced the Booth, the companion Shubert, and the Longacre Theaters.
He also studied fireproofing methods and aided the New York City Fire Department in developing building codes[1] and designed the Guggenheim family mausoleum at Salem Fields Cemetery in Brooklyn.
