John Shaw, the husband of Biocon executive chairperson Kiran Mazumdar Shaw, passed away on Monday at the age of 73.

Shaw, former vice-chairman of Biocon, was being treated in a Bangalore private hospital, where he passed away on Monday, company officials said.

He was under treatment for cancer for some time.

“With profound grief, we inform you of the passing away of John Shaw, husband of Kiran Shaw and former vice-chairman of Biocon today morning,” an official said.

Kiran Shaw lost her mother Yamini Mazumdar, also an entrepreneur, to cancer in June this year.

A Scotsman and Indophile, John Shaw headed textile manufacturer Madhura Coats before joining Biocon in 1999. He served as the vice-chairman and non-executive director for over 22 years, before retiring in July 2021.

It was in 1998 that Kiran Mazumdar married the 1949- born John Shaw.
