First Omaha Securities, Inc.

First Omaha Securities, Inc., was one of the early pioneers in the discount brokerage business.

The company started as an investment banking business named Rahel, Knack and Co. in the 1960s in Omaha, Nebraska. It was purchased in 1975 by J. Joseph Ricketts, Robert Perelman, and David G. Kellogg, renamed First Omaha Securities, and became one of the first firms to offer negotiated commissions.

Ricketts acquired the company completely from the other two founders in 1981. The company became AmeriTrade Clearing in 1983. In March 1997, Ameritrade became a publicly held company. In 2005 Ameritrade acquired TD Waterhouse and was renamed TD Ameritrade.
