John M. (Jack) Mack and brother Augustus F. Mack purchase the carriage and wagon factory Fallesen & Berry. 

William C. Mack, who had operated a wagon-building plant in Scranton, PA, joins his brothers in the business. Carriage-making is phased-out, and the brothers focus on wagons. The Mack brothers begin experimenting with steam and electric motor cars. 

The brothers opened their first bus manufacturing plant in 1900. They introduced their first successful vehicle -- a 40-horsepower, 20-passenger bus. Mack Brothers Company is incorporated in New York with John M. Mack, Augustus F. Mack, and William C. Mack as the directors. 

1900 -1960 
Mack produced many different types and models of buses from the first Mack produce in 1900 until 1960. 

Mack Brothers Company begins using "Manhattan" as the trade name for their motorized vehicles.

Allentown, Pennsylvania became the home of the main manufacturing operations of the new Mack Brothers Motor Car Company. Mack was one of the first manufacturers to mount a cab directly over the engine, which increased driver visibility and maneuverability. Mack built rail cars and locomotives from 1905 until 1930. 

The "Manhattan" trade name is dropped, and trucks begin carrying "Mack" nameplate. The Manhattan Motor Truck Company incorporated in Massachusetts to operate several dealerships in that state. Charles Mack, the fifth brother, joins Mack Bros. Mother Car Co. 

In August of 1911, the brothers sold the company, and the new owners continued operation as the International Motor Company - a holding company for the Mack Brothers Motor Car Company and the Saurer Motor Company, another truck manufacturer which had a plant in Plainfield, New Jersey. The two truck manufacturing companies continue as distinct organizations, but the selling and servicing of Mack and Saurer trucks is combined as a distinct function of the holding company. 

The International Motor Company's size increases with the addition of the Hewitt Motor Company, a New York City based builder of highly engineered motor trucks. John and Joseph Mack, who'd been directors of the International Motor Company, leave. 

The Hewitt nameplate is discontinued. The Manhattan Motor Truck Company (which ran the Mack branches in New England) becomes the Mack Motor Truck Company. The Mack AB was the company's first standardized, high volume model series, introduced in 1914. 

The famous AC model was introduced in 1916. The story goes that the British soldiers ("Tommies") would call out when facing a difficult truck problem, "Aye, send in the Mack Bulldogs!" The primary, and generally universal, story is that the British engineers testing AC's and the Tommys in France said that "the Mack AC's have the tenacity of a bulldog." At that time, the symbol of Great Britain was the bulldog, and this was high praise for the trucks. American "Doughboys" expressed the same opinion of the truck. 

The Saurer nameplate is discontinued in the United States. Mack became the first truck manufacturer to apply air cleaners and oil filters to trucks after Mack engineers discovered the fuel and maintenance savings these products offered customers. 

The title of the parent company is changed from International Motor Truck Corporation to Mack Trucks, Incorporated. to lessen any misidentification of Mack products with those of a competitor, the International Harvester Company. The International Motor Company continues as the manufacturing subsidiary of Mack Trucks, Inc. until 1936. In 1922, the company adopted the Bulldog as its corporate symbol. The first usage of the Bulldog as a symbol was on a sheet metal plate riveted to each side of the cab. It was first drawn on June 3, 1921 and was released, printed, and specified for the AB chain drive (CD) and dual reduction (DR) carrier drive trucks. The plate shows the Bulldog as two words, i.e., a bull dog chewing up a book entitled "Hauling Costs," "Mack" on his collar, and International Motor Co. of New York. 

Early in 1932, Alfred Fellows Masury, Mack's Chief Engineer, was admitted to the hospital for an operation. Masury was one of those individuals who wasn't used to his hands being idle for any period of time. During his recuperation in the hospital, Masury decided to carve a bulldog. (Some rumors indicate that he carved the first bulldog from a bar of soap; other rumors indicate the first was carved from wood.) Whether the first bulldog hood ornament was soap or wood, we do know that shortly after his release from the hospital, he did in fact carve a bulldog in wood. Masury applied for and received a patent for his design; that Bulldog design has adorned Mack trucks ever since! 

The name of the International Motor Company is changed to the Mack Manufacturing Corporation. Mack was one of the first truck manufacturers to apply four-wheel brakes to heavy-duty trucks, increasing braking ability and safety, particularly with heavier loads. In 1938, Mack became the first truck manufacturer to design and build its own heavy-duty diesel engines, establishing the tradition of "balanced design" 

During the war years, Mack built heavy-duty trucks to support the Allied forces. 

Mack changes the titles of its manufacturing and sales subsidiaries to Mack Trucks, Inc. 

Mack Trucks, Inc. becomes a member of the Signal Oil and Gas Company, a Los Angeles based petroleum company. In August 1967 Mack Trucks, Inc. officially became a member of a growing industrial family, The Signal Companies, Inc. 

In 1969, Mack pioneered and patented cab air suspension as a major truck ride and cab durability improvement. Mack was the first heavy-duty diesel engine manufacturer of the day to produce its own engine compression brake -- the patented Dynatard engine brake in 1971.

New Mack World Headquarters opens in Allentown, Pennsylvania. 

Mack Trucks, Inc. again became a public corporation in 1983 with a public offering of 15.7 million shares of Mack Trucks, Inc. 

Mack Trucks, Inc. becomes a wholly-owned subsidiary of Renault V.I. The company became one of North America's largest producers of heavy-duty diesel trucks, in addition to major product components, and is an integral member of the worldwide Renault Group.

On December 18, 2000 the United States Department of Justice approved the acquisition of Mack by AB Volvo, Sweden.

When the first Volvo truck rolled off the production lines in 1928 it was shaft-driven, had pneumatic tires and the driver sat in a fully enclosed cab. Even at this early stage in truck development, Volvo trucks were built to a very high standard in terms of their reliability and quality.

This was a decade of growing success and improved products for Volvo. Although its first generation of trucks looked old-fashioned, Volvo soon caught up with more well-established manufacturers. Volvo started to produce trucks that ran on diesel fuel, trucks with steel wheels instead of wooden spoke wheels, trucks with efficient hydraulic brakes and heavy-duty Volvo trucks soon became commonplace on the roads of Sweden and selected export markets. 

The first half of the 1940s was, of course, dominated by World War II. Volvo’s production of vehicles for the private sector fell sharply, but sales of advanced cross country vehicles to the Swedish Army more than made up for the absence of private customers. The experience would prove to be of great long-term benefit in the design and production of other forms of rough terrain vehicles that would be used in areas such as construction. During the late 1940s, production of old-fashioned pre-war vehicles increased dramatically. 

Volvo acted as a pioneer of the turbocharged engine and the emergence of stronger, more efficient engines contributed to heavier and longer truck combinations. The introduction of sleeper cabs and power-assisted steering made life easier for the driver and as a whole the importance of truck transportation increased. 

The truck was finally crowned transportation king. This was due in no small part to its flexibility and the fact that a national and international road infrastructure was in place that enabled fast, safe and efficient truck transportation. The 1960s was, in other words, a good decade for drivers. In Sweden, certified safety cabs were launched on the market. Cabs were fitted with rubber suspension systems, drivers enjoyed the benefits of sitting on sprung seats, and the new high F/COE-cabs afforded superb visibility. 

More European manufacturers were beginning to fit their trucks with tilt-cabs (a move pioneered by Volvo in 1962) and turbocharged engines (Volvo had been the first back in 1954). The horsepower rating of engines also grew, resulting in increased average speeds. The decade also saw the emergence of a new breathtaking series of trucks that would set the trend of truck design for years to come: the Volvo F10/F12 (and the Globetrotter version). 

Most cabs were modelled on the Volvo F10/F12/Globetrotter. Engines became better, stronger and, above all, more environmentally-friendly. And with increased use of air suspension systems, roads, goods and drivers enjoyed a much more comfortable life. Furthermore, with the introduction of new legislation and the continuing process of international harmonisation, not only were trucks able to provide optimal transport efficiency as a sole means of transport, but also in combination with other forms of transportation such as railways, shipping and air transport. 

This era led to more efficient vehicle combinations and (at the end of the decade) we saw the integration of IT-solutions such as Volvo Dynafleet 2.0, which provides haulage companies and drivers with tools that increase the efficiency and safety of each journey.With top priority being given to cleaner emissions and low noise levels, engines were refined and, in a few cases, totally new engines were introduced.

The diesel engine trucks will continue to be the most flexible and efficient transport tool, but new engine types will complement the diesel engine for special tasks. In addition to this, the emergence of integrated IT-systems and increased cooperation between different forms of transportation (including trucks, railways, shipping and air) have contributed to even better transport solutions. The Volvo group is a publicly traded company with Renault as its largest shareholder.
