Beloved instructor and trainer Martin Luther Neff died at his home in Norristown, Pa. He was 80.

Mr. Neff was born in Berks County, Pa., and moved to England in his early life. He served in the Korean War, where he was wounded, before relocating to Pennsylvania, where he became a farm manager and instructor.

A dedicated horseman, Mr. Neff was well-known for his love of the horse, as well as his endless hours of working with local Pony Clubs and 4-H groups. From eventing to western, he was able to adapt his methods to any rider or horse.

“He had forgotten more about the nature of the horse than most of us will ever learn,” said former student Sarah Winckelman. “He taught me more about horses than anyone in my life.”

His focus turned to dressage in the later years of his life, but he remained a highly regarded Pennsylvanian horseman until his death.

Mr. Neff was the youngest of five children and never married. He is survived by the students and horses that he inspired through the years.
