Ross married Rosa Bessie Bloxam in 1889. They had two sons, Ronald and Charles, and two daughters, Dorothy and Sylvia. His wife died in 1931. Ross survived her until a year later, when he died after a long illness, at the Ross Institute , London, in 1932.

In India Ross is remembered with great respect. Because of his relentless work on malaria, the deadly epidemic which used to claim thousands of lives every year could be successfully controlled. There are roads named after him in many Indian towns and cities. In Calcutta the road linking Presidency General Hospital with Kidderpore Road has been renamed after him as Sir Ronald Ross Sarani. Earlier this road was known as Hospital Road. In Hyderabad, the famous Quarantine (Koranti) hospital is named as Sir Ronald Ross Institute of Tropical and Communicable Diseases in recognition to his services in the field of tropical diseases.

G.N. Ramachandran

Gopalasamudram Narayana Iyer Ramachandran, or G.N. Ramachandran,

(8 October 1922 - 7 April 2001) is widely acknowledged as one of the most important Indian scientists of the 20th century, best known for his work that led to his creation of the Ramachandran plot for understanding peptide structure. He was the first to propose a triple-helical model for the structure of collagen. He also made other major contributions in biology and physics.

Professor Ramachandran was born in the town of Ernakulam, Kerala, India. He joined the Indian Institute of Science, Bangalore in 1942 in the Electrical Engineering Department. Gopalasamudram, the native place of his forefathers, is a village in the old Tirunelveli District of Madras Presidency. Quickly realizing his interest in physics, he switched to the Department of Physics to complete his master's and doctoral thesis under the supervision of Nobel laureate Sir C. V. Raman. In 1942 he received a master's degree in physics from Madras University with his thesis submitted from Bangalaore (he did not attend any Madras college at that time). He subsequently received his D.Sc. degree in 1947.[1] Here he mostly studied crystal physics and crystal optics. During his studies he created an X-ray focusing mirror for the X-ray microscope. The resulting field of crystal topography is used extensively in studies involving crystal growth and solid-state reactivity.

Ramachandran then spent two years (1947–1949) at the Cavendish Laboratory in Cambridge, where he earned his Ph.D. for 'studies on X-ray diffuse scattering and its application to determination of elastic constants' under the direction of Professor Wiiliam Alfred Wooster, popularly known as W.A. Wooster, a leading crystollagraphy expert in the world.

S. Chandrashekhar.

(S. Chandrashekhar. By Kameshwar Wali, Imperial College Press , 1997)

Subrehmanyam Chandrashekher was an austere, diligent and patient scientist and a very humane person. He was born in 1910. In 1930 he sailed to Cambridge University, England. While in the ship , he worked out the fate of collapsing stars. Stars less than 1.4M _Ө after burning out their nuclear fuel collapses into white dwarf where electrons are tightly packed to their spatial limit and develop degeneracy pressure which halts further collapse. But stars heavier than 1.4M _Ө overcome this degeneracy pressure and collapse into neutron star. Chandrashekher had correctly predicted that Supernova remnant will be a neutron star.
