Geoffrey Douglas Langlands CMG, MBE, HI, SPk (21 October 1917 – 2 January 2019) was a British educationalist who spent most of his life teaching in and leading schools in Pakistan, instructing many of the country's elite.

[4][5][6][7][8] Langlands was born in 1917, with a twin brother,[9] in Hull, England, to a father employed in an Anglo-American company and a mother who was a classical folk dance instructor.

[12] In January 1944, Langlands arrived in British India as an army volunteer on a troop carrier and worked three years as part of the selection board for officers training in Bangalore.

Rising to the acting rank of troop sergeant major, he received an emergency commission in the British Indian Army as a second lieutenant in the Garhwal Rifles on 3 September 1944.

[3] In 1979, the Chief Minister of the Northwest Frontier Province (now Khyber Pakhtunkhwa) offered Langlands the post of principal at Cadet College Razmak in North Waziristan.

By the time Declan Walsh reported on the man and the school in 2009, it was clear that standards had slipped, and the financial situation was parlous; the district's top official said Langlands was "A brilliant teacher but not a good manager.

"[21] Eventually another principal was found, and Langlands reluctantly agreed to move to grace and favour accommodation on the grounds of Aitchison College, as it was thought that he could do more good for the Chitral school by fundraising in the capital.

[28] Eventually scores of the college staff boarded a school bus for the 1000 km drive to Lahore, where they met with Langlands and persuaded him to allow Schofield to continue her work.

In a tweet he paid tribute: "Apart from being our teacher, he instilled the love for trekking and our northern areas in me - before the KKH (Karakoram Highway) was built".

In a career lasting 60 years, he has sought to maintain the ethos of the English public school in an alien land, long after the sun set on the empire he served.
