While attending Harvard Business School, Bill Berkley and his partner formed Berkley Dean & Company – an investment management company that was the precursor to W. R. Berkley Corporation – with a $2,500 investment.

In the early 1970s, the company entered various aspects of the insurance business and debuted as a public company.

In 1972, the company entered the insurance market through the acquisition of Houston General Insurance Company. In 1973, the Union Insurance Company was organized in Nebraska, while Traders & General Insurance Company was acquired.

The company went public as W.R. Berkley Corporation on October 19, 1973, just hours before the Arab Oil Embargo was announced and later sold Traders & General Insurance Company while organizing Tri-State Insurance Company of Minnesota and acquiring Union Standard Insurance Company.

From the mid to late 1970s, the company marked three important milestones.  In 1975, W. R. Berkley Corporation instituted a policy of paying a regular cash dividend.

That same year, the company entered the reinsurance market by organizing Signet Reinsurance Company and acquiring Reinsurance Underwriters Corporation.

In 1979, the company entered the specialty insurance market through the purchase of Admiral Insurance Company.

Through the early 1980s, the company continued to grow its regional, specialty and reinsurance businesses, and added an insurance service provider to its portfolio of companies.

In 1982, W. R. Berkley Corporation acquired Firemen’s Insurance Company of Washington, D.C., and later the hard market in 1985 and 1986 provided several opportunities to expand. 

In 1985, Carolina Casualty Insurance Company was acquired, Firemen’s Habitational Division was established to write coverages for high-end real estate in the northeast, Facultative ReSources was formed to write casualty facultative reinsurance, and Nautilus Insurance Company was formed to write smaller excess and surplus lines risks.

Regional operations expanded in 1986 with the acquisition of Continental Western Insurance Company, and Clermont Specialty Managers was formed from the Firemen’s Habitational Division. The company also entered the risk management and administration services sector by forming Berkley Risk Administrators Company.

By 1987, the company’s total assets surpassed the $1 billion mark, total revenues exceeded the half-billion dollar level, and net worth rose above the one-quarter billion-dollar mark.

In the early 1990s, the company continued to grow through both acquisition and the formation of new companies.

Acadia Insurance Company in Maine, Chesapeake Insurance Division of Firemen’s Insurance in Virginia, and Great River Insurance Company in Mississippi were all established to further expand the regional business.

New acquisitions included Midwest Employers Casualty Company and a controlling interest in La Union Gremail de Seguros S.A. in Argentina.

At the turn of the century, the company refined its strategy. The regional companies were consolidated to reduce costs, enhance size and scale, and to provide better competitive positions, while maintaining operations close to the customer. This segment was also repositioned to emphasize commercial lines of business and targeted niches, while withdrawing from personal lines.

The company’s reinsurance segment withdrew from commodity-type reinsurance, such as pro-rata and property lines, to focus on specialty businesses.

It also formed Preferred Employers Insurance Company, which provides workers’ compensation coverage for small employers in California.
