Network Marketing pioneer Jay Van Andel has passed away at age 80.

From the Detroit Free Press:

He died Tuesday at his home in Ada, just east of Grand Rapids, according to
Amway’s parent company, Alticor Inc. The cause of death was not disclosed but
Van Andel had Parkinson’s disease, a disorder of the central nervous system that
involves a degeneration of nerve cells in parts of the brain.

His wife, Betty Van Andel, died Jan. 18 at 82 at the family home on Peter
Island in the Caribbean. She had Alzheimer’s disease and had been in declining
health for some time.

Jay Van Andel and Amway co-founder Richard DeVos reshaped their hometown of
Grand Rapids over the years with their investments and donations. Many of the
buildings and institutions in Michigan’s second-largest city bear one of their
names.
