Caterpillar
A supplier to Caterpillar Inc. since the 1970s, Perkins was bought by Caterpillar in 1998 for US$1.325 billion, creating what they claimed was the world's largest diesel engine manufacturer. With an ever-expanding global footprint Perkins now has manufacturing facilities in the United Kingdom, United States, Brazil, China, India and a joint venture with Ishikawajima-Shibaura-Machinery company in Japan. On January 1, 2009 (replacing Hans Haefeli), Gwenne Henricks became President of Perkins Engines[5] after having worked in Caterpillar’s Electronics and Connected Worksite Division in North America. Gwenne is also a vice-president of Caterpillar.[6]
