IN: Kosciuszko was born in February 1746 in a manor house on the estate called "Mereczowszczyzna" near Kosow, (now Kosava, Belarus) in Nowogrodek Voivodeship, Grand Duchy of Lithuania, a part of the Polish-Lithuanian Commonwealth. His exact birthdate is unknown; commonly cited are February 4 and February 12. Kosciuszko was the youngest son of a member of the szlachta (nobility), Ludwik Tadeusz Kosciuszko, an officer in the Polish-Lithuanian Commonwealth Army, and his wife Tekla, nee Ratomska. The Kosciuszkos held the Polish Roch III coat of arms.

After traveling south through rural Virginia in October 1780, Kosciuszko proceeded to North Carolina to report to his former commander General Gates. However, following Gates's disastrous defeat at Camden on August 16, 1780, the Continental Congress had selected Washington's choice, Major General Nathanael Greene, to replace the disgraced Gates as commander of the Southern Department. When Greene formally assumed command on December 3, 1780, he retained Kosciuszko as his chief engineer. By then, he had been praised by both Gates and Greene.  Over the course of this campaign, Kosciuszko was placed in command of building bateaux, siting the location for camps, scouting river crossings, fortifying positions, and developing intelligence contacts. Many of his contributions were instrumental in preventing the destruction of the Southern Army. This was especially so during the famous "Race to the Dan", when British General Charles Cornwallis chased Greene across 200 miles (320 km) of rough back country in January and February 1781. Thanks largely to a combination of Greene's tactics, and Kosciuszko's bateaux, and accurate scouting of the rivers ahead of the main body, the Continentals safely crossed each river, including the Yadkin and the Dan. Cornwallis, having no boats, and finding no way to cross the swollen Dan, finally gave up the chase and withdrew back into North Carolina. The Continentals regrouped south of Halifax, Virginia, where Kosciuszko had earlier, at Greene's request, established a fortified depot.  During the Race to the Dan, Kosciuszko had helped select the site where Greene eventually returned to fight Cornwallis at Guilford Courthouse. Though tactically defeated, the Americans all but destroyed Cornwallis' army as an effective fighting force and gained a permanent strategic advantage in the South. Thus, when Greene began his reconquest of South Carolina in the spring of 1781, he summoned Kosciuszko to rejoin the main body of the Southern Army. The combined forces of the Continentals and Southern militia gradually forced the British from the back country into the coastal ports during the latter half of 1781 and, on August 16, Kosciuszko participated in the Second Battle of Camden. At Ninety Six, Kosciuszko besieged the Star Fort from May 22 to June 18. During the unsuccessful siege, he suffered his only wound in seven years of service, bayonetted in the buttocks during an assault by the fort's defenders on the approach trench that he was constructing.  Kosciuszko subsequently helped fortify the American bases in North Carolina, before taking part in several smaller operations in the final year of hostilities, harassing British foraging parties near Charleston, South Carolina. He had become engaged in these operations after the death of his friend Colonel John Laurens, taking over Laurens's intelligence network in the area. He commanded two cavalry squadrons and an infantry unit, and his last known battlefield command of the war occurred at James Island, South Carolina, on November 14, 1782. In what has been described as the Continental Army's final armed action of the war, he was very nearly killed as his small force was routed. A month later, he was among the Continental troops that reoccupied Charleston following the British evacuation of the city. Kosciuszko spent the rest of the war there, conducting a fireworks display on April 23, 1783, to celebrate the signing of the Treaty of Paris earlier that month.

input: Kulwicki began his racing career as a 13-year-old kart racer. His father built engines as the crew chief for Norm Nelson and Roger McCluskey's United States Automobile Club (USAC) racecars. Because his work involved travel, Kulwicki's father was unable to help his son at most kart races, so Kulwicki's resourcefulness was often tested trying to find someone to transport his kart to the track. Even when Kulwicki asked his father for advice, he typically ended up doing most of the work himself. "I showed him how", Gerry Kulwicki said. "And he said: 'Why don't you do it? You can do it better.' And I said, 'Well, if you do it for a while, you can do it better.'"  Many local-level American racetracks host their own season championships. In Wisconsin, numerous locations held dirt and asphalt short track racing. Kulwicki started driving stock cars at the local level at the Hales Corners Speedway and Cedarburg Speedway dirt oval tracks. In 1973, he won the rookie of the year award at Hales Corners Speedway in the Milwaukee suburb of Franklin, and the next year started racing late models - the fastest and most complicated type of stock cars raced at the local level - at the same track. That season, he won his first feature race, at Leo's Speedway in Oshkosh.  Kulwicki moved from dirt tracks to paved tracks in 1977. He also teamed up with racecar builder Greg Krieger to research, model, engineer, and construct an innovative car with far more torsional stiffness than other late models. The increased stiffness allowed the car to handle better in the corners, which increased its speed. Racing at Slinger Super Speedway, he won the track championship in 1977. In 1978, Kulwicki returned to Slinger; that same year he started racing a late model at Wisconsin International Raceway (WIR), finishing third in points in his rookie season at the track. In 1979 and 1980, he won the WIR late model track championships.  In 1979, Kulwicki began competing in regional to national level events sanctioned by the USAC Stock Car series and the American Speed Association (ASA), while remaining an amateur racer through 1980. When Kulwicki raced against future NASCAR champion Rusty Wallace in the ASA series, the two became friends. Kulwicki's highest finish in the ASA season points championship was third place, which he accomplished in both 1982 and 1985, with five career victories and twelve pole positions.
