Robert Toll, who built Toll Brothers into the country’s largest luxury homebuilder and brought a founder’s passion to the business, died Friday at age 81 after suffering from Parkinson’s disease

The entrepreneur, who was known as Bob, and his brother Bruce founded Toll Brothers (ticker: TOL) outside Philadelphia in 1967. They initially constructed two homes that they decided to hold as samples for lots they were developing nearby.
