June 7, 2026, marks the 72nd death anniversary of Alan Mathison Turing, the mathematical genius, World War II hero, and a visionary universally regarded as the father of modern computing and Artificial Intelligence (AI). Turing’s extraordinary intellect helped shape the modern world, which is now inextricably linked to our day today lives. Yet Alan Turing’s life was cut tragically short, at a young age of 41, due to the cruel discrimination and archaic laws that criminalised his homosexuality.
His story must serve as a powerful reminder - and not merely find a historical footnotemention - of the heavy price societies pay when prejudice triumphs over rationality and humanity. As we remember Alan Turing today, in the month of June which happened to be the month of his birth and death (b.23.06.1912 and d.07-06.1954), India’s journey from the colonial-era stigma to a relatively better social inclusion offers hope and underscores the need for continued reform.
Born in London on June 23, 1912, Alan Turing was a prodigy whose prophetic ideas transcended his time. His seminal 1936 paper, “On Computable Numbers, with an Application to the Entscheidungsproblem”, introduced the concept of the universal Turing machine. This theoretical foundation laid the groundwork for programmable computers and the algorithms that now power everything from smartphones and servers to advanced AI systems today. During World War II, at the historic Bletchley Park — the very site that hosted the inaugural Global AI Summit in 2023 — Turing led a team that cracked the formidable German Enigma codes using a electromechanical machine, Bombe, which they built.
The success of the Bombe machine helped the British military top officials to advocate that mechanising the code breaking process was highly effective. Historians estimate this the Bombe breakthrough shortened the war and saved millions of lives. Turing’s wartime service was nothing short of heroic. The effectiveness of Bombe in cracking “German Enigma Codes” created an institutional confidence for further funding the war activities in Bletchley Park and to greenlight building automated machines for cracking the German Lorenz Cipher – used in transmitting, strategic military orders at the top level generals. The result was the development of arguably the world’s first programmable electronic computer – Colossus. Notwithstanding his monumental contributions, Turing was not spared of his dignity.
In 1952, British authorities prosecuted Turing for “gross indecency” following a consensual relationship that he had with another man. Faced with the stark choice between prison and chemical castration through hormone treatment, he opted for the latter to preserve his ability to continue his scientific work. The humiliation, loss of security clearance, and unrelentingsocietal stigma proved unbearable for Turing. On that fateful day, June 7, 1954, Turing was found dead from cyanide poisoning, with a half-eaten apple lying beside him. Whether his death was deliberate suicide or accidental poisoning remains debated, but the role of state-sanctioned prejudice is undeniable. That half-eaten apple - lying by his bedside at the time of his death - has since become symbolically linked - perhaps unwittingly - to the iconic Apple Inc’s logo, a poignant memory of both loss and enduring technological inspiration.
Turing’s personal connection to India adds a profound layer of resonance. His father, Julius Mathison Turing, served as an Indian Civil Service officer in the Madras Presidency from 1896. His mother, Ethel Sara Turing, was the daughter of Edward Waller Stoney, chief engineer of the Madras Railway Company, who constructed notable infrastructure projects, including the sprawling bungalow “The Gables” in Coonoor in the Nilgiris. Turing’s elder brother, John, was born there, and it is widely believed that Alan himself was conceived in India (then part of the Madras Presidency) before his birth in London while his parents were on leave. Decades later, Nandan Nilekani — co-founder of Infosys and the architect of Aadhaar — purchased that same Coonoor bungalow. The symbolism is striking: from Turing’s foundational contributions to computing to Nilekani’s digital identity revolution that empowered 1.4 billion Indians through the JAM Trinity (Jan Dhan, Aadhaar, Mobile), enabling unprecedented financial inclusion and direct benefit transfers.
This legacy is vividly alive today, in 2026. India hosted the fourth edition of the Global AI Impact Summit at Bharat Mandapam in New Delhi earlier this year, following the 1st, inaugural event, at Bletchley Park. The Indian AI ecosystem is exploding, with generative AI alone projected to grow at an estimated staggering growth of 42% CAGR, and the broader market expected to reach $126 billion by 2030. From AI-driven crop prediction for farmers and personalised healthcare to climate modelling and India’s strategic security requirements,Turing’s vision is powering India’s digital transformation. Yet the man who first embedded logic into machines that could “think” was himself denied the freedom to live with dignity. Incidentally, in the year 2018, the Nehru Science Centre, Mumbai, which I then headed, we had opened a new exhibition “Machined to Think” - on the eve of National Technology Day – in which Turing’s beautifully sculpted Sculpture reminded visitors of his contributions.
The discriminatory laws of the British that hounded Turing also manifested in India as Section 377 of the Indian Penal Code, 1860. This law criminalised “carnal intercourse against the order of nature.” For generations, this colonial relic, coupled with deep-rooted societal prejudices, silenced LGBTQ+ individuals, shamed divorced women, ostracised those struggling with mental health, and pushed countless young people facing academic or professional failure to the brink of despair. The pervasive fear of “log kya kahenge” (what will people say?) paralysed families and stifled individual liberties.
A historic turning point came on September 6, 2018, when a five-judge Constitution Bench of the Supreme Court of India, led by then Chief Justice Dipak Misra, unanimously struck down the application of Section 377 to consensual adult same-sex relations. The Times of India captured this historic judgment with its front-page banner: “INDEPENDENCE DAY – II.” In landmark observations, the court described members of the LGBTQ+ community not as aberrations but as natural “variations” of humanity. Senior advocate Dr Menaka Guruswamy, who argued passionately before the court alongside her partner Arundhati Katju, played a pivotal role in this victory.
It is heartening to witness India’s quiet revolution of dignity. In April 2026, Dr Guruswamytook oath as a Rajya Sabha MP, becoming the country’s first openly queer parliamentarian — a full-circle moment of justice and visibility. Around the same time, a retired judge in Meerut, Gyanendra Kumar Sharma, welcomed his divorced daughter home with a full band-baaja, garlands, sweets, and matching “I Love My Daughter” T-shirts. He declared that her dignity mattered more than societal gossip. These events are incremental yet transformative sociocultural milestones, signalling a shift from stigma and silence to public acceptance.
As someone who has spent over four decades communicating science through museums and public platforms, I have witnessed first-hand how prejudice masquerading as tradition erodes the scientific temper, humanism, and spirit of inquiry enshrined in Article 51A(h) of the Indian Constitution. Parents of children with mental health challenges still face whispered ostracism. Students who fail exams or drop out are often pushed towards despair. The same social poison that once targeted Turing and generations of LGBTQ+ Indians continues to claim young lives in subtler forms.
Turing’s tragic end, abetted by societal prejudice and outdated laws, reminds us of what societies lose when they weaponise morality against difference. His story compels us to reflect on the preventable loss of genius and potential. Yet, the progress we witness today — legal, constitutional, and increasingly social — is slow but heartening. From the 2018 judgment to recent milestones of acceptance, India is slowly embracing a more inclusive ethos.
On this solemn anniversary, let us honour Alan Turing not only for his monumental contributions to computing and AI but also for the resilient human being he was. His half-eaten apple symbolises both profound loss and an enduring call to inspiration. We must remember the precious price paid due to discrimination and commit to ensuring no future innovator or citizen faces such barriers.
Appreciating the societal changes underway, we must nevertheless solicit and accelerate more. True inclusion requires fuller legal protections in areas such as marriage, adoption, and workplace equality; robust mental health support systems; and everyday acts of empathy that dismantle the lingering “log kya kahenge” mindset. Education, policy reform, and cultural dialogue are essential to nurture a society where every individual — regardless of sexuality, marital status, gender identity, or personal setbacks — can contribute fully without fear.
Turing’s legacy, intertwined with India’s digital ambitions and its evolving social landscape, lights the path forward. Let us draw strength from his brilliance and resolve to build a more humane, just, and scientifically tempered future — one where dignity is not a privilege but a fundamental right for all.
