G.D.Naidu was born in a Kamma naidu family at Kalangal, near Coimbatore. His Father's name was Gopalaswamy Naidu.
On one fine day there was a British driving a motor cycle to his Kalangal village. While others were amused by the foreigner; young Gopalswamy was inspired by the motor cycle. He longed that somehow he should drive it. Being driven by his thoughts he ran away from his village and joined as a waiter in a hotel in Coimbatore. He worked there for three years and saved up to 400 rupees. Meanwhile he came to know the whereabouts of the British who was a surveyor. He went to that surveyor and dropped his 400 rupees at his feet. Seeing the never giving attitude of the young boy the surveyor gave him the motor cycle. Ecstatic young Doraiswamy drove it and also learned everything by dismantling and assembling the motor cycle and later became a mechanic. He began his transport business in 1920, with the purchase of an automobile coach. He drove it between Pollachi and Palani. In a few years, his United Motor Service (UMS) owned the most efficient fleet of public transport vehicles in the country.In 1937, the first motor to be produced in India, was brought out from G. D. Naidu's factory "NEW" (National Electric Works) at Peelamedu, Coimbatore
