Google today celebrates 135th birth anniversary of Sarojini Naidu with a doodle dedicated to her. The doodle on the search giant's home page has a portrait of Sarojini Naidu in the place of the second 'O' in the company's logo. There's also a pen in place of the letter 'L' in logo, which seemingly depicts Naidu's writing capabilities. 

Known as The Nightingale of India, Naidu was the first Indian woman to become the president of the Indian National Congress. Naidu joined Indian national movement after the partition of Bengal in 1905. In 1925, Naidu presided over the annual session of Indian National Congress at Cawnpore. She played an active role during Civil Disobedience Movement and Quit India movement. 

Born as Sarojini Chattopadhyay on February 13, 1879 in Hyderabad, Naidu was eldest among eight siblings. A daughter of a poetess, Naidu had great interest in poetry right from childhood days. Her first collection of poems titled 'Golden threshold' was published in 1905. 

A meritorious student, Naidu topped the matriculation examination at Madras University. She received her higher education from King's College London and later at Girton College, Cambridge.

At the age of 19, she married Dr Govindarajulu Naidu. 

British government awarded Naidu Kaiser-i-Hind medal for her work during the plague epidemic in India. 

Naidu died of a heart attack on March 2, 1949 at Lucknow. 

Google marked the Winter Games in Sochi by flying the gay flag on Thursday in a search page Doodle that linked to a call for equality in the Olympic Charter.

Showcasing the flag and the excerpt served as an online rebuttal to Russian Deputy Prime Minister Dmitry Kozak, who warned spectators and athletes against promoting gay rights during the Olympics, saying it was forbidden by the Olympic Charter and Russian law to spread propaganda during a sporting event.

Beneath the Rainbow Flag was the following paragraph attributed to the Olympic Charter:

"The practice of sport is a human right. Every individual must have the possibility of practicing sport, without discrimination of any kind and in the Olympic spirit, which requires mutual understanding with a spirit of friendship, solidarity and fair play."

Clicking on the Doodle triggered a search for news related to the Olympic Charter, with stories about what was being interpreted as a Google protest of an anti-gay atmosphere caused by officials in the host country of Russia.

Google declined to comment.

Amid growing furor over Russia's new law forbidding the dissemination of "gay propaganda" to minors, Kozak once again argued that there was no discrimination based on sexual orientation in Russia.

President Barack Obama told US Olympic host broadcaster NBC he had included openly gay athletes in the US Olympic delegation to show the United States would not accept discrimination in sport or anywhere else.

One day ahead of the official opening of the Games, UN Secretary-General Ban Ki-moon made a powerful call for equality, saying "we must all raise our voices against attacks" on gays.
