Biographical sketch

The Port Authority announced the design of the World Trade Center in 1962, groundbreaking began in 1966, and tower construction started in 1968 with both of the Twin Towers completed by 1973. In 1967 the Mosher Steel Company of Houston was awarded a four million dollar contract to supply the core columns and box beams for 14 floors of each tower. Mosher shipped 13,000 tons of steel, with the largest piece weighing 55 tons. These core columns were part of the World Trade Center's innovative structural design that included a perimeter of multiple tube columns tied back to columns in the core.
