Martin ("Marty") E. Zweig was a legendary investor, writer, and teacher, known for his prediction of the 1987 Market Crash. He died on February 18, 2013.
Zweig was born in 1942 in Cleveland, Ohio. He began trading stocks as a teenager, and in the 1970s began his more formal career as an investment newsletter writer while working at the same time as a professor of Finance. His newsletter, "The Zweig Forecast" was published for 26 years (1971-1997) and was one of the most highly regarded investment newsletters in the United States. 
He is also credited with original and important statistical market research, including the creation of the put/call ratio, a technical measure of investor sentiment that is now a common market indicator.
Zweig's writings include a book about his investment strategy, "Winning on Wall Street", as well as articles he contributed to business magazines such as Barron's. During the 1980s, Zweig was a frequent guest on PBS's "Wall $treet Week with Louis Rukeyser". During an appearance in 1987, Zweig famously and accurately forecast the October 1987 stock market crash. 
Zweig was also a collector of pop culture items. Some notable pieces of his collection include the dress Marilyn Monroe wore to serenade "Happy Birthday" to former US President John F. Kennedy, the Hofner bass guitar played by Paul McCartney, and a Jackie Robinson 1947 rookie Brooklyn Dodger jersey (the only one known in existence). 
Zweig graduated from Wharton in 1964 with a B.A. in economics. He later received an MBA from the University of Miami and a Ph.D. in finance from Michigan State University.
