The item is a group photo of Dr. Anil Kumar Das, Prof. K. R. Ramanathan, and other employees of the Kodaikanal Observatory with astronomer Royal from Kodaikanal Observatory in 1947. K. R. Ramanathan was an Indian physicist and meteorologist. He was the first Director of the Physical Research Laboratory, Ahmedabad.

The item contains a photograph related to the visit of Russian astronomers to the Kodaikanal Observatory on 19 January 1955. The photo shows four Russian scientists and the staff of the Kodaikanal Observatory.

The item is related to the visit of Prof. Sydney Chapman to the Kodaikanal Solar Physics Observatory on 1948 December 31. Sydney Chapman was a British mathematician and geophysicist who contributed to the kinetic theory of gases, solar-terrestrial physics, and the Earth's ozone layer. The photo shows Prof. Chapman and Dr. Anil Kumar Das, the observatory's director, sitting with the other staff. The visit of Prof. Chapman was a noteworthy feature of that year.

The photograph of A. A. Narayana Ayyar was taken in 1913 at Solar Physics Observatory, Kodaikanal.

This item was about John Evershed (1911-1923) who joined Kodaikanal Observatory in 1907 as the Assistant Director and became the Director in 1911. In 1909, Evershed discovered that there is radial outflow of gases in a sunspot. This effect is now Known as the "Evershed Effect". For this seminal work, he was elected to the Royal Society in 1915 and was awarded the Gold Medal of the Royal Astronomical Society in 1916.

This item was about the Norman Robert Pogson in 1861. N.R. Pogson was appointed the government astronomer at Madras, India. When he arrived he had to work under harsh conditions. He found the instruments in a bad shape and there were no proper staff to assist him. In spite of all these he began a series of observations which terminated with his death 30 year later. He as credited with 50,000 observations most of which were published by Michie Smith after Pogsons death. During his stay in Madras he discoverd several minor planets and detected large number of variable stars. He named his daughters after the minor planets he discovered. He was also well known for his work in comets and solar eclipses.
