Kahn created a style that was monumental and monolithic; his heavy buildings for the most part do not hide their weight, their materials, or the way they are assembled.
He was awarded the AIA Gold Medal and the RIBA Gold Medal.
At the time of his death he was considered by some as "America's foremost living architect."
In 1974, on his return home from the subcontinent, Kahn was overcome by a heart attack in the men's bathroom of Penn Station in New York City, where he died tragically alone at the age of seventy-three.
Five years later, the family emigrated to Philadelphia, and the name was changed to Kahn to sound more like the German Jews who had been part of Philadelphia society for generations and not like newly arrived (and invariably poorer) Russian Jews.
