A mass tort is a civil action involving numerous plaintiffs against one or a few corporate defendants. The tort may involve, for example, personal injuries suffered by numerous plaintiffs as a result of a defective product, or a mass disaster in which there were many injured persons, such as an airplane crash, or exposure of a large group of people to toxic chemicals or pharmaceuticals.
Waltham is a city in Middlesex County, Massachusetts, United States, billed by the Chamber of Commerce as the "birthplace of the American industrial revolution", and an early center for the labor movement. The original home of the Boston Manufacturing Company, the city was a prototype for 19th century industrial city planning. The city is now a center for research and higher education, home to Brandeis University and Bentley University. The population was 59,226 at the census in 2000. Waltham is commonly referred to as Watch City because of its association with the watch industry. Waltham Watch Company opened its factory in Waltham in 1854 and was the first company to make watches on an assembly line. It won the gold medal in 1876 at the Philadelphia Centennial Exposition. The company produced over 40 million watches, clocks and instruments before it closed in 1957.
