Robert G. (Gilmour) LeTourneau

(The comments below are excerpted from Mr. LeTourneau's obituary.)

Robert G. LeTourneau was born on November 30, 1888, to godly parents. From infancy he heard the Gospel. For a time, he rejected the message, but through the faithful prayers of his parents he was, at the age of sixteen, won to Christ. At 30 he dedicated his life to be God's businessman. He recognized the danger of that dedication being dimmed by his love for his machines, but by the grace of God that commitment extended over a period of fifty years.

He designed and built machines beyond the imagination of ordinary men. He introduced into the earthmoving and material handling industry the rubber tire, which today is almost universally accepted. He invented and developed the Electric Wheel. He pioneered the welding of various metals. His huge mobile offshore drilling platforms are supporting the machines that drill for the rich petroleum reserves under the seas around the world.

He demonstrated his concern for the Gospel witness by establishing regular chapel services and by employing three full-time Chaplains in his manufacturing plants. The monthly publication NOW begun by him reached 600,000 persons during his lifetime and circled the world with its message. He s traveled the world as a witnessing Christian businessman.

Many books about his life have published, including his best-selling autobiography, Mover of Men and Mountains (Zondervan), which is still in print, thirty years after his death. This book has been translated from English into several foreign languages. Who can tell how many have come to faith in Christ through his missionary ministry in Liberia, West Africa and Peru, South America? The outreach for God through aid to individuals and organizations by the LeTourneau Foundation has been worldwide.

LeTourneau University which he, together with his wife, founded may well prove to be one of his greatest accomplishments as his influence is multiplied and spread throughout the world by dedicated Christian young people who have studied at the college.

His life's verse was Matthew 6:33: "Seek ye first the kingdom of God and His righteousness and all these things shall be added unto you."

R.G. LeTourneau's last patent was granted on July 13, 1965, when he was 77 years old. In the 42 years between these two inventions he was granted 297 more patents and became one of the top inventors of all time.

These 299 inventions included the bulldozer, scrapers of all sorts, dredgers, portable cranes, rollers, dump wagons, bridge spans, logging equipment, mobile sea platforms for oil exploration, the electric wheel and many others.

LeTourneau built 70% of the heavy earthmoving equipment used by the allies in World War II. During the height of the war, from 1942 to 1945, his fertile mind pumped out 78 inventions, many of which were instrumental in helping to win the war.

Although LeTourneau had only a few years of formal education, his prodigious inventive efforts were recognized with dozens of industrial awards and he was presented with honorary doctorate degrees from five different colleges and universities.


R. G. LeTourneau felt that he was clearly led by to to business as his calling. The workplace was his mission field. It was as "God's businessman" that he pursued his reason for existence: to glorify God and spread the Gospel message.

His ministry, however, was not limited to business enterprises. At his own expense, he founded missionary efforts in Liberia, Africa and Peru, South America that encompassed evangelistic as well as economic initiatives. He traveled around the nation and the world preaching and sharing his testimony at his own expense as well. Visitors to the R. G. LeTourneau Museum frequently recall the impact these messages had on them and their family members.

Mr. LeTourneau always felt that his lasting spiritual legacy would be the college he and his wife founded in Longview, Texas in 1946. The college--now LeTourneau University--continues to hold to its spiritual foundations and has produced more than 20,000 alumni who are faithfully serving the Lord in all 50 states and 40 nations. The mission continues to grow and thrive as LeTourneau alumni claim every workplace in every nation as their mission field.
