Klein was born in Chicago and was raised in the city's Ravenswood neighborhood. A multi-sport letterman at Roosevelt High School, he also began writing as a high school student. Klein attended the University of Illinois at Urbana-Champaign and wrote both for the student Daily Illini and for the Champaign-Urbana Courier. Graduating from Illinois in 1959, Klein entered Harvard Law School, but left after a term to pursue journalistic opportunities and graduate work at the University of Michigan.
In 1962, Klein joined the staff of the Pittsburgh Press, and joined the Wall Street Journal's Pittsburgh bureau in 1963, first covering the steel beat. Moving on to the Journal's main office in New York in 1967 and to the Chicago bureau in 1969, Klein increasingly focused on writing some of the newspaper's signature Page One features. Sports became an increasingly frequent topic of his Page 1 items, and in 1977, Klein was named the first-ever sports columnist for the Journal, a role he held into 2001. From 2001 to 2003, Klein was a columnist with Sports Business Journal.
Klein's first book, Education of a Horseplayer, was published in 1968. It was followed in 1974 by News & The Market, written with, which focused on the impact of news on share prices.

He has also co-written several sports-related autobiographies, and his columns have been included in anthologies published by the Journal over the years.
Currently in semi-retirement, Klein is dedicating his energies to environmental preservation and the publication of the "For The Love Of..." series of illustrated sports books. The series includes books about Golf, Baseball, the Chicago Cubs, the New York Yankees and the Boston Red Sox.
