Mari Hulman George was named to the position of vice president and board member.
When Mary F. Hulman's health began to decline, she retired and was named chairman emeritus, a position she held until her death in 1998.
The chairmanship of the companies was passed to Mari Hulman George in 1988.
Mari Hulman George held those positions until the summer of 2016.
Shortly after the 2016 Indianapolis 500, Mari was facing declining health and was elected chairman emeritus of the family companies.
