- J._Leonard_Johnson abstract "James Leonard Vincent "Len" Johnson (1905–1966) was an American scientist."Len" Johnson was an American engineer, designer, and scientist in the mid-twentieth century in the field of metallurgy and nuclear technology. He was one of the first Irish Catholics to break into the exclusive field of design engineering for the Department of Defense.Len Johnson was born in Freeland, Schuylkill County, Pennsylvania in 1905. Though from an Irish family, Len was actually the 4th generation in the US. His great grandfather had immigrated from Moneyneana, County Londonderry, Ulster, Ireland in 1839, prior to the great Irish Famine. However, his roots in Pennsylvania and in America went back to the early 1700s.The first member of his family to come to America was, Sir William Johnson (McShane) who originally came to the colony of New York in 1720. He managed his uncles properties and eventually created his own estate called Johnstown (town), New York. William rose to prominence in the French and Indian War as the Commissioner of the Iroquois tribe. He created and led an army of Indian and settler soldiers at various battles rising to the rank of Major General in the British army in America. The Battle of Lake George in 1755 earned him a baronet title and his capture of Fort Niagara with his Indian troops defeating the French army made him, "Johnson of New York". It is still an active baronetcy within the family. His grandmother was Ada "Mary" Wilson. Her family had been originally come to the US in the 1750s as Quakers outside Philadelphia. Len had an early grandfather, Captain Joseph Greene, who commanded the Northumberland County Ranger company at the close of the American Revolution in 1782, and had served in the York County militia from as early as 1777. Through his grandmother he was also a close cousin to President Woodrow Wilson.His grandfather John was a collier engineer in Freeland, Pennsylvania, and his uncle, Captain Patrick Johnson, was an officer in the 116th Infantry Regiment of Pennsylvania, of the Irish Brigade and had fought at the Wheatfield at Gettysburg. Both were regionally famous musicians. His father, John Joseph "Jack" Johnson was the first Irish boss of the huge Cox Coal Company. It is estimated that Jack Johnson directed over 1000 workers on a day-to-day basis spanning six major installations to include a railroad. As a young man he was selected to be the first Irish boss and was educated by the company. After his formal education he was placed in charge of the entire field. That position allowed his son, Len, to enter into the prestigious Mining and Mechanical Institute (now MMI Preparatory School) from which he was graduated in 1922.From there, Len became the first of his family to attend college. He chose to attend Pennsylvania State College (now University) and graduated with a degree in Mechanical Engineering in 1926. What to do after graduation proved to be a difficult decision to make in that he was offered a job with the professional baseball team system, the St. Louis Browns. He was a particularly good 2nd baseman and was playing semi-professional baseball at the time for the Allentown Dukes. However, he chose to go into engineering full-time, returning to the coal fields and went to work for Bethlehem Steel company through the 1920s. Len's work with new casting designs brought him greater attention and was eventually notice by U.S. Steel. In the 1930s he was hired and went to work for a US Steel affiliate, the National Tube works in Lorain, Ohio and then to McKeesport, Pennsylvania, where he became the General Manager of the entire plant. While there he wrote numerous articles on the advancements of steel use in the defense industry. He stayed until the late 1930s when he rose to become a designer of new steel products, leading the transition away from casting to the use of rolled steel.".
