Wallace R. Weitz started his Wallace R. Weitz & Co. in 1983, just 13 years after graduating from Carleton College with his BA in Economics. Weitz uses a value investing philosophy which has evolved over the years. Wally Weitz has been called Omaha's Other Oracle, for insistence on value investing and his consistently high returns - and the fact he moved to Omaha, of course. Weitz says the move was because he didn't want to raise his kids in New York City and he chose Omaha because that's where his wife is from. That's not to say Buffett wasn't influential in Weitz's life. Berkshire remains his firm's largest holding. He owned 1,499,160 shares in the company at the end of the third quarter, 2011.
