At age 23, he started a meat-packing business and earned a reputation for being honest and hard-working. During a later war in 1812, Wilson gained a position inspecting meat for US Army forces, working with a man who had signed a contract with the government to provide meat to the army. Barrels of meat supplied to the army were stamped "EA-US", identifying the company EA and the country of origin US. According to one story, when a government official visited the plant and asked about the letters, a creative employee told him "US" was short for "Uncle Sam" Wilson. Soon soldiers were saying all Army supplies were from "Uncle Sam".
23岁时，他开始从事肉类加工业，并因为人诚实、工作勤奋而赢得声誉。 此后在1812年的战争中，威尔逊获得了一个职位，为美国军队检验肉食。他的合伙人和美国政府签订了一份合同，给军队提供肉食。送到军队的肉桶上面都印有EA-US标志，EA代表公司名，US代表原产国。传说有一回，有个政府官员来参观加工厂，问及这些字母的含义，一个想象力丰富的雇员告诉他，“US”是“山姆大叔”威尔逊的缩写。很快，士兵们都说所有的军需品都来自“山姆大叔”。
