His writings earned him the title of National Artist in 1987, and the 100th anniversary of his birth was celebrated by the UNESCO in 2003 as recognition of his contribution to the advancement of education in Thailand and Southeast Asia.

Another often-recounted story from his childhood is that of how, before having learned to count, when his mother asked him to gather half a bunch of betel leaves for her, Pin set down to picking up one leaf with each hand at a time, separating them equally into two piles.

[6] At the age of four, Pin began receiving preliminary education from teachers who came to teach at the family home on Damrongrak Road, next to Varadis Palace.

The Royal Page Students were involved in plays and sports games held in court and also in activities of the King's scouting-related paramilitary movement, the Wild Tiger Corps.

[11] In 1922, when Pin was eighteen years old, the Ministry of Public Instruction, in accordance with the King's wishes, granted him a government scholarship for a tertiary education in ancient Eastern languages in the United Kingdom.

He also developed a taste for opera and classical music, on which he recalled spending quite a disproportionate amount of his scholarship's allowance, eventually building a collection of 317 records.

Upon return to London, he attended the First World Conference on Adult Education on behalf of Siam, but during the same time his health deteriorated further, and he was diagnosed with tuberculosis.

There he spent almost two years in Davos and later Klosters, until September 1931 when he attended the League of Nations annual conference before returning to Siam via a Nippon Yusen ship departing from Naples, Italy.

Upon Pin's return from Europe in 1931, Public Instruction Minister Prince Dhani Nivat appointed him as a government official under Krom Vichakan, a department of the ministry.

Under the Prince's directions, Pin became an instructor in mathematics, Thai, and English at Chulalongkorn University, in addition to the various duties he performed for the ministry.

During his term as director, which lasted until 1944, he developed and implemented a fixed class schedule system, along with a mechanical timetable used to assign teaching periods, which is still in use today.

[4][28] As World War II reached Thailand in December 1941, Japanese troops raided and occupied the school, forcing teachers and students to evacuate and relocate to temporary locations around Bangkok, and later to various other provinces.

Although resources were limited due to the war, Pin was able to manage the budget and personnel to allow a countrywide 12 baht salary for rural local schoolteachers.

In this capacity, he oversaw the founding in 1949 of the Higher Teacher Training School at Prasanmit, now Srinakharinwirot University, and the drafting of the first national education plan.

He served as director and coordinator for the Seminar on Rural Adult Education in Mysore, India, that year, and regularly represented Thailand in subsequent UNESCO meetings.

He facilitated the establishment of UNESCO's regional office in Bangkok, which opened in 1961, and was among the founders of the Southeast Asian Ministers of Education Organization.

There he intended to established a collegiate university system following that used at Oxford, as advised when he was Permanent Secretary of Education by Prime Minister Pibulsonggram, and Thap Kaew College was opened in 1968.

[43] As minister, Pin also oversaw the construction of the Bangkok Planetarium, which opened in 1964, and of the new National Library building at Tha Vasukri, and the revival of the King's Scholarship, among other things.

[46] The group's work continued, and the Fine Arts Department established it into an official committee, with Pin as chairman, to make preparations for the 100th anniversary of the King's birth, which would be recognised by UNESCO.

[47][48] The committee also conducted research on the Wild Tiger Corps, and determined the location in Photharam District, Ratchaburi Province, of Ban Rai, where King Vajiravudh often set up camp with them.

Pin initiated the construction there of a statue of the King in Wild Tiger Corps uniform, which was unveiled in 1988, and the surrounding area was developed into Khai Luang Ban Rai scout camp, which also contains a medical station and kindergarten.

UNESCO celebrated the centenary of his birth in 2003, recognizing the value and impact of his contributions to the development of education in Thailand and Southeast Asia, and to the literary arts and the safeguarding and conservation of historical monuments and sites.
