JPMorgan Chief Executive Jamie Dimon lost both his parents to cancer earlier this week.

Veteran Wall Streeter Theodore “Ted” Dimon passed away on June 5 at the age of 85. Themis Dimon, his wife of 65 years, died a day later, on June 6, at the age of 84, according to WSJ.com.

After a wave of mergers and acquisitions, the elder Dimon ended up working for his son when Jamie rose to become chairman and CEO of Smith Barney in January 1996.

Ted Dimon was reunited with his son again at JPMorgan and worked in the office until a few months before his death, WSJ.com reported.

Ted Dimon became a stockbroker at Shearson Hammill in 1953, starting out as an assistant for his father, a year after his marriage to Themis Anastasia Kalos, the report said.
