Marcus was known industrywide for his passion, personality and keen knowledge of the industry and where it was headed.
 
“The steel industry was Peter’s passion, inspiration and neverending endeavor,” WSD said in a statement.
 
Marcus graduated from Cornell University in 1960 and received an M.B.A. from New York University in 1965. He began his career on Wall Street in 1961 with L.F. Rothschild & Co.
 
After 28 years at PaineWebber, Marcus and his World Steel Dynamics staff formed their own separate company in 1999.
 
According to WSD, Marcus believed the steel industry was the “fundamental building block for economic prosperity – the ‘engine’ of the virtuous upward cycle that would ultimately benefit one and all; his words and actions embodied this belief.”
 
He leaves behind several “families,” his colleagues said: his personal family, his WSD family, and WSD’s “family” of clients and industry friends, all of whom he loved immensely.
