Donaldson, Lufkin & Jenrette was a U.S. investment bank founded by William Donaldson, Richard Jenrette and Dan Lufkin.
The bank was formed in 1967 as the market was in serious need of high quality market research. The firm offered investment and merchant banking, financial advisory services, investment research, venture capital, interactive brokerage services, and asset management. The company also dealt in high yield fixed income securities in both underwriting and trading.
The bank was bought by Credit Suisse in July 2000.
