JEEP-- a vehicle invented to be used in war that grew into one of the world's most recognized automotive brands. Jeep's early history is legendary. Its role in helping defeat the Axis powers during World War II is undeniable.

The birth of Jeep took place more than 75 years ago. On July 16, 1941, Willys-Overland Motor Co., of Toledo, Ohio, received the first contract to produce the Willys MB for use by the American military.

As World War II began to ravage Europe and Asia, the War Department realized the armed forces needed a small reconnaissance vehicle. It put out requests for proposals to U.S. automakers on an extremely aggressive timetable.

The first prototype military Jeep was developed by Bantam. Designed in 18 hours by Karl Probst, a freelance auto designer from Detroit, the 1,840-pound Bantam exceeded the Army's expectations during initial testing in September 1940.

The War Department, however, had concerns about Bantam's ability to meet the military's capacity needs. As a result, it invited Willys-Overland and Ford Motor Co. to bid on the reconnaissance vehicle contract, this time using Probst's design as a guidepost and allowing engineers from the two automakers to inspect and measure the Bantam.

Each automaker crafted a vehicle that was intended to meet the War Department's specifications -- but with varying success. The Willys Quad had the most powerful engine -- the 60-hp Go Devil four-cylinder, which gave it a significant power advantage. The Ford Pygmy had superior craftsmanship, and it featured a flat hood and flat fenders that the War Department judged as useful improvements. The Bantam, now updated from its original design, was the lightest and most fuel-efficient.

After conducting rigorous testing in Maryland, the War Department sought final bids and awarded the first production contract to Willys-Overland. A second production contract for the same design later was awarded to Ford to meet demand.

More than 637,000 Jeeps were built by Willys and Ford during World War II, while Bantam was awarded a contract to build quarter-ton trailers that were pulled behind the MB. Even today, remnants of Jeeps birth by committee exist on the MBs descendent, the Jeep Wrangler. For example, the Tlatches still used to hold down the hood were a Ford innovation, as was the single-piece, stamped slotted grille with round headlights that Jeep also uses as a logo.

On the battlefield, the Jeep was fast, nimble and tough. It could handle nearly any terrain, and when it did get stuck, it was light enough for soldiers to lift free. It towed anti-tank weapons that could be deployed quickly, and it could mount a machine gun for fighting infantry.

The Jeep also served as an ambulance on the battlefield, as it traversed rivers and lakes. It came ashore on D-Day and carried the Allies all the way to Berlin, onto the Guadalcanal, Iwo Jima and eventually onto the mainland shores of a defeated Japan.

As World War II began to wind down, Willys executives began thinking about the Jeeps postwar existence. Willys took the MB and modified it, improving the headlights and seats and giving it a tailgate. The production version became the Willys CJ-2A. It also introduced other innovative vehicles, including the 1946 Willys Station Wagon -- the first such station wagon to be built completely of steel -- and the 1947 Jeep pickup.

Willys-Overland had always had a policy to sell at least 15 percent of its production for overseas sales, even way back into the 1920s,  But the other thing that helped was that, what Willys did was really the ultimate free sample: When World War II ended, the Army left Jeeps all over the world.

In the decades following World War II, Jeep retained a small but loyal civilian following and remained largely reliant on its military contracts for volume and profitability.

It continued to develop innovative civilian designs -- such as the 1957 FC-170 (for Forward Control), the 1963 Wagoneer SUV and 1963 Gladiator pickup -- while further developing its line of Jeep military vehicles.

However, Jeep's ownership structure wasn't stable. Willys-Overland was purchased by Kaiser Manufacturing Co. in 1953. In 1963, the company dropped the Willys name, becoming Kaiser-Jeep Corp. Six years later, in 1969, the company was acquired by American Motors.

AMC was not in strong financial shape when it acquired Jeep. In 1978, French automaker Renault purchased 25 percent of the struggling domestic automaker.

Jeep sales were a strong point in the AMC lineup, and it was under AMCs ownership that one of the most innovative and popular Jeep vehicles, the XJ Cherokee, was developed. Designed by Roy Lunn and Bob Nixon, the XJ Cherokee that debuted for the 1984 model year was a unibody SUV, something no other automaker had ever done. The XJ's simple, boxy shape drew classic styling cues from Jeep's heritage, but its design was elegant, and its off-road capabilities were unmatched by anything short of a Jeep CJ.

Though modifications were made over its long production life, the XJ Cherokee's production ran for 18 years -- through two subsequent ownership changes -- until 2001 and totaled over 2.7 million vehicles.

Jeep's string of owners tended to struggle. From Bantam to Willys to Kaiser to AMC, each corporate entity that had acquired Jeep had subsequently failed -- more often than not for reasons that had little to do with Jeep.

Yet Iacocca coveted Jeep. He recognized that the off-road brand complemented Chryslers  offerings. We aren't just combining our strengths. We're increasing them,the former Chrysler chairman declared when Chrysler purchased AMC for $1.5 billion. Chrysler used its resources to improve existing products such as the XJ Cherokee, and in 1992, introduced the ZJ Grand Cherokee by driving it through a plate-glass window at the Detroit auto show.

And as Jeep's popularity grew, so did Chrysler's profitability. The No. 3 U.S. automaker had become a potent global player with the addition of Jeep and consumers’ nearly limitless demand for SUVs.

Ultimately, Chrysler drew interest from Daimler AG and in 1998, combined with Chrysler in a $38 billion merger of equals.

 Which celebrities are driving Jeeps?

The Daimler Chrysler era saw some of the best-ever Jeep decisions, including new, modern assembly plants as well as the addition of two rear doors to the Wrangler to create the Wrangler Unlimited.

But it also witnessed some of the worst, including development of the carlike, Jeep-in-name-only Compass and Patriot, which featured front-wheel drive and continuously variable transmissions

Less than a decade later, Daimler paid $675 million to Cerberus Capital Management to take Chrysler -- and Jeep -- off its hands. And two years after that, Chrysler, including Jeep, sought bankruptcy protection and had to be rescued by the government.

Yet Chrysler was able to emerge from its 2009 bankruptcy in large part because Fiat S.p.A. CEO Sergio Marchionne recognized the value of Jeep as well as its global potential

Marchionne first set out to fix problems in Jeep's lineup. He improved the Compass and Patriot and invested in the Grand Cherokee, improving its interior, electrical architecture and powertrain. He killed the Jeep Commander and green lighted replacement of the unloved Liberty with the revived Jeep Cherokee, the first Jeep built on a Fiat platform.

Under Fiat, Jeep has added a subcompact, the Renegade and expanded the Wrangler family by including a pickup, The Gladiator.

One weak corporate owner after another failed, yet Jeep soldiered on. Today, Jeep carries Fiat Chrysler Automobiles as the automaker compete with more powerful, profitable global competitors.
