BOSTON – Timothy Matlack Warren Sr., who led the business and real estate publishing company that bears his family’s name, has died nearly a year after he was diagnosed with a progressive blood disorder, his son said. He was 89.

Warren, chairman of Boston-based The Warren Group, died Friday at home in Topsham, Maine, surrounded by family.

The death left the family brokenhearted but proud of Warren’s life of service and accomplishment, his son Timothy Warren Jr. said in a statement Wednesday.

The Warren Group was founded in 1872 and Warren joined the family business in 1948 as a printer’s apprentice. He eventually became president and publisher and since 1988 was chairman of the board. He turned the flagship publication Banker & Tradesman into a leading industry voice. His son said he helped reshape information available to the real estate industry.

Warren was diagnosed in January with myelodysplastic syndrome.

He was raised in New Canaan, Conn., and Lovell, Maine, and after serving during World War II, completed his education at Bowdoin College.

He is survived by his wife of 66 years, Phyllis, three children, six grandchildren and two great-grandchildren.

A memorial service was scheduled for the First Parish Church in Concord on Jan. 4.
