Overview of Cleveland’s Millionaire Row.
“There is a stretch of Cleveland’s Euclid Avenue (US Route 20) that was once known as the most beautiful street in America. It was also known as “Millionaire’s Row”, because in the late 1800s to the early 1900s the street contained the homes of some of the richest and influential people in the city and the county. Some of the names of the families who lived on “Millionaire’s Row” included those of industrialist and philanthropist John D. Rockefeller; banker and industrial distributor George Worthington; arc light inventor Charles F. Brush; mining magnate Samuel Mather; industrialist and politician Marcus Hanna; John Hay, personal secretary to Abraham Lincoln and Secretary of State under William McKinley; and Jeptha Wade, founder of Western Union Telegraph.”
