Gehendra was born in Poush, 1928 BS. He was born in the Indian city ofKolkata where his father was sent to serve as the Nepali representative to India. Born in a noble Rana family, he had the rare privilege to study. Apart from being privately tutored within the palace in English, he later also attended Durbar High School – the oldest modern school of Nepal. With the enrollment in Durbar High School, his interests were kindled, now that he was trying his hand at sports and music as well. However, past Durbar High School, not much is known about his academic part of life. While some references suggest he was sent to Japan along with 5 others to pursue engineering studies, his precise academic qualification remains unknown. As a kid, Gehendra was intimately drawn to mechanics and ammunition. After the murder of Ranodip Singh Kunwar in 1942 BS, his father, Bir Shumsher, became the nation's prime minister, and opportunities popped up for him. At a tender age of 14 years, he was appointed to take care of the ammunition department in the Royal Nepal Army. This early exposure gutted in him a lifelong fascination for arms, ammunition, and the like.
Career
At some point, Gehendra Shumsher worked as a spy chief and the head of police, but his interests were largely confined to the manufacture and design of firearms. As opposed to importing arms and ammunition from other countries, he wanted to manufacture them within the country, especially by exploiting locally available raw materials like iron and coal. So, after a considerable study of British catalogues, he set up manufacturing factories at Jamal, Sundarijal, Balaju, and Megchan with a view of doing just that. Towards the end of 1956 BS, Gehendra Shumsher imported a motor car from Ford Motor Company. He tried to make a new motor car himself by disassembling and studying every part in every detail. Besides, he set up a seven boiler rice mill and wind motor to draw underground water at Seto Durbar, the residential palace he inherited from his father. He was the first man in Nepal to produce electricity in Nepal. He demonstrated how electricity could be produced with the help of water. In addition, he also set up a leather tanning factory in Balaju. Gehendra Shamsher is credited for modernization of Nepal Army. He was able to make his own mechanical machine gun similar to Gardner gun and named it Bira gun after his father. He is also credited for modifying Martini–Henry into new gun Gahendra Martini and Ge-rifle, a double-barrelled machine gun. Besides, he also developed a new model of canon Dhir-Gun, named in honour of his grandfather, Dhir Shumsher.
Later life
After the demise of Bir Shumsher, Dev Shumsher ascended to the throne. Dev and Gehendra Shumsher shared an amicable relationship, so Gehendra had an important position in the palace. He was appointed as the spy chief and head of police. Later, upon the request of Dev Shumsher, he went to Japan to study the Japanese technology, especially with regard to the manufacturing of firearms. Gehendra Shumsher died a mysterious death at the age of 35. However, it is believed that during initial years of Chandra Shumsher's premiership, Gehendra Shumsher was murdered at his residence in Seto Durbar as Chandra was scared of his political and military influence.
