Olmsted returned to Des Moines in 1946. The management team that he had built in his companies before leaving for military service had performed well during the war years and his return became a matter of picking up where he had left off. After an unsuccessful bid for the Republican nomination for governor of Iowa in 1947, International Bank (IB) was headquartered in a building at 1701 Pennsylvania Avenue (diagonally across from the Old Executive Office Building and the White House) in Washington and controlled the activities of several companies which were separated into five operating groups: • The Life Insurance Group – United Services Life Insurance Company/Bankers Security Life Insurance Society. • The Property and Casualty Insurance Group – Hawkeye-Security Insurance Company and the other insurance companies in Des Moines. • The International Maritime Group – The International Trust Company of Liberia which administered the registration of vessels under the Liberian flag. • The International Banking Group – Ownership interests with local partners in commercial banks in 10 foreign countries. • The Industrial Group – Globe Industries, Kliklok Corporation, Avis Industrial Corporation, and a 16% ownership of Foster Wheeler Corporation. In December 1972, International Bank (IB) bought a two thirds stake in the Mercantile Bank & Trust Company which had a bank in
Freeport, Bahamas, the Mercantile Bank of Freeport, and another bank in the
Cayman Islands of a similar name. However, following the death of Helliwell on December 24, 1976, the banks Castle, Mercantile (Nassau) and Mercantile (Cayman) collapsed in the middle of May 1977. Castle had been under the IRS's "Project Haven" investigation due to over three hundred Castle clients supposedly involved in a tax evasion scheme. In 1980, Helliwell's Castle Bank was revealed to be a
CIA account for the Helliwell law firm. In addition to Helliwell supposedly being one of the pay masters for the
Bay of Pigs invasion of Cuba in 1961, Castle had been one of the CIA's financing channels for operations in Latin America and against Cuba between 1964 and 1975 which included CIA operatives located on
Andros Island,
Bahamas. Financial General was a domestic bank holding company which held controlling interests in 26 banks located in seven states and the
District of Columbia. It was one of the few banks in the country that had been grandfathered to do business across state lines after the
McFadden Act largely banned interstate banking. In 1966, following years of criticism from other banks, the Federal Reserve ruled that Financial General was a bank holding company, and as such could not be owned by International Bank (which despite its name was largely an insurance company). Olmsted was ordered to sell off Financial General by 1978. It eventually went to a group of Arab investors who were actually nominees for the
Bank of Credit and Commerce International. This group changed FGB's name to First American Bankshares, which would remain a secret subsidiary of BCCI until the latter's shutdown in 1991.
Community support Throughout his career, Olmsted worked with colleges and universities and sought to enhance the availability and quality of higher education for all people. He served on the board of trustees at
Drake University in Des Moines, the American University in Washington, the West Point Association of Graduates, the West Point Alumni Foundation, and from 1973 to 1978, at the appointment of
President Nixon, on the Board of Visitors at West Point. He received honorary degrees from several universities: Doctor of Laws –
Drake University. Doctor of International Relations –
Southeastern University. Doctor of Business Administration –
Iowa Wesleyan College. Doctor of Commercial Science –
Coe College. Camp Olmsted at
Goshen Scout Reservation is named after George H. Olmsted. ==George and Carol Olmsted Foundation==
