History
Huntingdon Life Sciences was founded in the UK in 1951 as Nutrition Research Co. Ltd., a commercial organisation that initially focused on nutrition, veterinary, and biochemical research. The original facilities were split over two locations; the main offices were within Cromwell House in the town of Huntingdon; and the main laboratories were at the Hartford Field Station, just over a mile away. It then became involved with pharmaceuticals, food additives, and industrial and consumer chemicals. In 1959 it changed its name to Nutritional Research Unit Ltd. The company benefited in the early 1960s from increased government regulatory testing requirements, especially in the pharmaceutical industry. In 1964, it was acquired by Becton Dickinson.[3]
In April 1983, Becton Dickinson created Huntingdon Research Centre PLC. It then offered four million American depositary receipts (ADRs) for sale at $15 each, representing the company's entire interest in Huntingdon. In 1985, as it began to expand its operations, the company changed its name to Huntingdon International Holdings plc. That year, it established Huntingdon Analytical Services Inc. to conduct business in the United States.
To augment its CRO business, Huntingdon acquired Minnesota's Twin City Testing Laboratory and affiliated companies in 1985, followed by the acquisition of Nebraska Testing Corporation in 1986; Travis Laboratories and Kansas City Test Laboratory Inc. in 1989; and Southwestern Laboratories, Inc. in 1990. Huntingdon also diversified its operations, primarily in the United States, becoming involved in engineering and environmental services.
In 1987, HLS acquired Northern Engineering and Testing. In 1988, it acquired Empire Soils Investigations, Chen Associates, and Asteco Inc. In 1988, HLS was floated on the London Stock Exchange and in 1989 obtained a listing on the New York Stock Exchange. In 1990, Huntingdon acquired the St. Louis branch of Envirodyne Engineers and Whiteley Holdings. In 1991, it acquired Austin Research Engineers, followed by Travers Morgan.
By the early 1990s, Huntingdon was organised into three business groups: the Life Sciences Group, the Engineering/Environmental Group, and the Travers Morgan Group, which offered engineering and environmental consulting services outside of the United States. However, only the Life Sciences Group showed long-term promise. Travers Morgan was allowed to lapse into insolvency, control passed into other hands, and Huntingdon wrote off the investment. In 1995, the engineering and environmental businesses were sold to Maxim Engineers of Dallas, Texas.
To bolster its CRO business and reinforce its U.S. presence, in 1995, Huntingdon acquired the toxicology business of Applied Biosciences International for $32.5 million in cash, plus the Leicester Clinical Research Centre. The deal included a U.S. laboratory located near Princeton, New Jersey, as well as two British facilities. In 1997, Huntingdon International Holdings changed its name to Huntingdon Life Sciences Group. The U.K. subsidiary, Huntingdon Research Centre, changed its name to Huntingdon Life Sciences, while the U.S. business operated as Huntingdon Life Sciences Inc.
In 2002, HLS moved its financial centre to the United States and incorporated in Maryland as Life Sciences Research.
In 2009, HLS was acquired.[4]
In September 2015, Huntingdon Life Sciences, Harlan Laboratories, GFA, NDA Analytics and LSR associates merged into Envigo (now Inotiv).
