    Robert Gilmour LeTourneau (November 30, 1888 – June 1, 1969), was born in Richford, Vermont, and was a prolific inventor of earthmoving machinery. His factories supplied LeTourneau machines which represented nearly 70 percent of the earthmoving equipment and engineering vehicles used by the Allied forces during World War II, and more than half of the 1,500 mile Alcan Highway in Canada was built with LeTourneau equipment. Over the course of his life he secured nearly 300 patents relating to earthmoving equipment, manufacturing processes and machine tools. The LeTourneau name became synonymous with earthmoving worldwide. LeTourneau was largely responsible for the invention and development of many types of earthmoving machines now widely used. He designed and built machines using technology that was years, sometimes decades, ahead of its time and became recognized worldwide as a leader in the development and manufacture of heavy equipment.

In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to what in forestry might be called timber theft by the timber mafia. It can also refer to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission or from a protected area; the cutting of protected species; or the extraction of timber in excess of agreed limits. Clearcut logging is not necessarily considered a type of logging but a harvesting or silviculture method, and is simply called clearcutting or block cutting.
