He and his brothers now headed the family business they started many decades ago.
Their company, Call Ready, is a sound service based in Old Dhaka.
Its black-white labels, mounted on microphones, are familiar sights in Bangladeshi meetings and conferences.
One of the most iconic moments in the country’s history also included a Call Ready microphone.
Ghosh, on the 97th birth anniversary of Bangabandhu Sheikh Mujibur Rahman, remembered how his father and uncle held on to the microphone the company had set up for his rally at Dhaka’s Race Course Maidan on Mar 7, 1971.
The nation’s father had used it to address a sea of people that day. His fiery calls for the nation’s independence is immortalised in history.
“My father and uncle wanted to give it to Bangabandhu. But that dream didn’t come true. No one listened when we tried to give these to the government.
“But we still want these preserved.”
Call Ready has been around for seven decades. It has provided sound services for meetings and rallies in remote places and amid difficult circumstances.
Two brothers set it up at Sutrapur’s Lakshmibazar.
Two more brothers helped them in their business. None of these Ghosh brothers – Dayal, Haripad, Gopal or Kanai – are alive.
Haripad’s four sons now run Call Ready. Among them Trinath was a director. Haripad passed away almost a
His uncle Kanai Ghosh died last year.
The Call Ready family now wants the mouthpiece from Bangabandhu’s most famous speech to be preserved in a museum.
Lights to sound
The brothers had inherited a cloth trade but they wanted to do more. So in 1948, they set up Arju Light house.
They rented out decorative lights and even gramophones. Arju Light House was soon the destination for people planning weddings and other events.
Call Ready was there in the meetings and rallies for the 1952 Language Movement, the United Front's movement in 1954, the six point movement in 1966, the 1969 mass uprising and election campaigns of 1970.
The Mar 7 rally
Bangabandhu had called Haripad and Dayal to his house in Dhanmondi, said Trinath.
He asked them to set up microphones at the Race Course Maidan for a mass rally to be held on Mar 7.
"They began working the day he called them. They hung speakers from tree branches and hid them under leaves so that they are not easily spotted."
The brothers did not care about being paid a labour fee for a rally of such significance, said Trinath.
"Carrying out what Bangabandhu said was the only important thing. My father had good relations with him so he would only take the rent fee. My father told me this."
'No one else'
"I'm so proud that Bangabandhu gave his speech using our sound system. Call Ready is everywhere in our nation's history," said Trinath.
