From the Tower Ticker:
Spector's decision to leave at the end of the year was announced Tuesday by the four-man executive council to whom he has been reporting since October's resignation of Randy Michaels as chief executive of the parent of the Chicago Tribune and other media properties.
Spector, 63, who first allied with [Sam] Zell as a 25-year-old accountant, held senior management roles in a number of Zell's ventures and played a critical role in building his property management company from scratch. He first became an officer of Equity Financial and Management in 1973.
Like his boss, Spector is a motorcycle enthusiast who traveled the globe as a member of Zell's Angels. A graduate of Roosevelt University and Senn High School, Spector spurned suits and ties for a colorful collection of sweaters but generally maintained a much lower profile than either Zell or Michaels.(found via FishbowlLA)
