Do you ever have an idea how Dyer breweries Company  came to be called Mohan Meakin Breweries?  India' s first Prime Minister, Jawaharlal Nehru, on an official visit to to Shimla in 1960.  Keenly interested in developing business opportunities in India, Pandit Nehru was particular about visiting industries in that region . Somebody advised him to visit  the Solan based brewery. Upon hearing this suggestion Nehru refused to visit the brewery for the simple reason the company was named after  Edward Dyer, whose son General Reginald Edward Dyer was associated with the gruesome Jallianwala Bagh massacre committed on the 13th of April 1919 (exactly 101 years from today).
“The refusal of PM Nehru served as the compelling reason to remove Dyer’s name,” recalls Lt Gen Pradeep Khanna (retd), whose father, Krishan Gopal Khanna, was the Financial Director with the company from 1959 to 1975''.
