John Summerville

The first name of Prof. Summerville is ambiguous. According to Morurahasya, his first name is Arthur, but according to Shonkur Shonir Dosha and Hypnogen his first name is John. It is possible that his first name is a combination of both. Just like his name, his area of specialization is also ambiguous. According to Aschorjo Prani, he is a Biochemist, but according to Shonkur Shonir Dosha and Hypnogen he is a Physicist. He is a close friend of Prof. Shonku, and has saved Shonku several times from deep trouble.

Apart from science, he is also a skilled hunter and has an excellent aim in pistol. Despite his old age, he is a strong man. This is seen in Shonkur Shonir Dosha, where he knocks out the domestic help of Prof. Finkelstein in just one punch.
