G. Iyer was a significant figure in the landscape of Indian journalism and social reform during the late 19th and early 20th centuries. Born in a Tamil Brahmin family, he displayed a keen intellect and a strong sense of social justice from a young age. His early education instilled in him a deep understanding of Indian culture and traditions, while his later exposure to Western thought shaped his progressive outlook.

Iyer's most notable contribution was his pioneering work in the field of journalism. He cofounded The Hindu newspaper in 1878, which quickly became a powerful voice for Indian nationalism and social reform. Through his incisive editorials and insightful reporting, he fearlessly challenged British colonial policies and advocated for greater Indian participation in governance. He also used the platform to champion causes such as women's education, widow remarriage, and the abolition of caste discrimination. His commitment to these ideals often placed him at odds with orthodox sections of society, but he remained steadfast in his convictions.

Beyond journalism, Iyer was actively involved in various social and political movements. He was a strong supporter of the Indian National Congress and played a key role in shaping its early agenda. He believed in the power of education to uplift the masses and worked tirelessly to promote literacy and learning. His efforts extended to establishing educational institutions and supporting charitable causes. Iyer's life was a testament to his unwavering dedication to the betterment of Indian society. He left behind a legacy of courageous journalism, progressive social reform, and selfless service to the nation. His contributions continue to inspire generations of journalists and social activists in India.
