A hustling Sikh Scientist of the 20th Century with a mystic poetic personality
On February 17, 1881, Professor Puran Singh was born in a mud hut in the Pathan village of Salhad, which is situated in Abbottabad (now Pakistan). His father, Kartar Singh was a revenue official. His mother, Param Devi, was a deeply devout Sikh practitioner. His early years were spent among the village's many waterfalls and lakes. Due to his father's profession, his family used to travel frequently . They made their home in Abbottabad, a hill town with a 3000-foot sea level. In the village of 'Havelian', a mosque served as his first school. At the age of twelve, he successfully completed his Anglo-Vernacular examination at a school in Haripur. The family later relocated to Rawalpindi where Puran Singh finished his high school studies . His mother pushed him to pursue his education because she wanted him to work for the government, as "a government officer on whose doors many men wait." He attended D.A.V. College in Lahore for four years before passing the F.A. Exam in 1899 in disciplines of English, Maths, Sanskrit, and Chemistry .
First Voyage & Educational Journey
Bhagat Golak Chand, his distant relative and a high school teacher, made the decision to send a few talented kids to Japan. Golak Chand saw him as a young child with a lot of talent and was eager to help him carve out a promising career. Puran Singh decided that he will go to Tokyo University in Japan to study Pharmaceutical Chemistry, but the family was in no position to bear the expenses . Therefore, Puran Singh sought help on his merit & awards by writing to all the Sikh elites of Rawalpindi, who agreed to contribute for his fee & travel. When his family learned of his plan to leave, they were devastated since they believed he would never come back. But he persuaded his parents of his desire to study and assured them that he would come back and end their poverty.
Damodar Singh, a close relative in the family, who also wanted to study, decided to major in electrical engineering and agreed to go with Puran Singh. The students took a ship that moved to Hong Kong and then to Singapore before arriving in Tokyo. Along the way, they had a lot of intriguing encounters and learned a lot. One most affecting incident which Puran Singh records in his autobiography  is when they had to eat half-boiled mutton with uncooked fat that stuck to it, or choose an unseasoned beef, and bitter coffee. Prior to arriving in Singapore, Puran basically went without food for ten days. On the last leg of his journey from Singapore to Tokyo, Puran Singh tried to settle with an option of eating chewy chicken and undercooked chapatis.
They landed at Yokohama in 1900 and were received by Mr. Ray and other Indian students. He studied at Imperial University, Japan, where he learned Japanese and German, as the medium of instruction was German. He graduated with a degree in Industrial Chemistry for Pharmaceutical Sciences in 1903 and then decided to go back to India .
Student Life in Japan
Puran Singh was a highly emotional man who adored everyone who came into contact with him. His upbringing helped him become empathetic. He was greatly influenced by nature and vegetation. He loved seeing the cherry blossoms in Japan, that brought him great delight and filled his heart with love. It would not be incorrect to label Puran Singh as an experimentalist who was easily influenced by new information and knowledge. He first converted to a Bhuddist monk (Bhiku) in Japan after being love-struck with Japanese culture, and then, after meeting Swami Rama Tirtha, he became a Vedantin in 1902 . Finally, he returned to India and attended the 5th Sikh Educational Conference conducted by Chief Khalsa Diwan, becoming a Sikh mystic under the influence of Bhai Vir Singh in 1912 .
Puran Singh had changed dramatically during his three years in Japan. He acquired his knowledge of science and business in Japan's academic and technical labs, which were primarily modeled after the German system. He also absorbed the Japanese artistic spirit. It was in Japan, that Puran Singh was drawn more deeply to poetry and was religiously practising the styles and norms of authors like Okakura Kakuzo and Walt Whitman. Puran Singh spent his days immersed in nature, poetry, japanese culture, music and art. His obsession with nature and mystic philosophies made him wander for knowledge and peace in all directions.
Return to India, Personal Affairs & Indian Revolution
Puran Singh brought back to India, a collection of blueprints for pharmaceutical and distillation equipment in 1903 from Japan . While studying in Japan, he started an Indo-Japanese club, which helped solidify relations between India and Japan. But his close associations with various revolutionaries like Mr. Kulkarni and Rama Kant Roy led to his arrest upon returning to India.
DISCLAIMER: Although the evidence is not clear, but facts below cannot be proven or disproven, as much of Puran Singh's life history is unaccounted by others.
Puran Singh was a member of the Oriental Club in Japan in 1900 and 1901. He gave numerous powerful speeches in support of Indian independence. He delivered a stirring lecture upon his return to India in 1903, for which he was sentenced to three months in prison. Despite being in the government, he supported Indian independence. His activist landlord kicked him out because he didn't enjoy the visits by revolutionaries like Ramaknat Rai. According to his wife, he also interacted with Lala Hardayal, Mr. Chatterjee, Kulkarni Maratha, and Dr. Khudadad. Due to the explosive nature of his lectures, Lala Hardayal fled India and later created the Ghadar party in America . With assistance from other Indians, he launched the Ghadar newsletter in San Francisco. Kartar Singh Sarabha oversaw its publication later.
In an unsuccessful attempt to assassinate Viceroy, Reshbihari, Puran Singh's lab assistant, stole picric acid from the facility and assembled a bomb with it. He later escaped to Japan, but Puran Singh had to pay his repercussions. He was facing a pretty strong case.
His supporters worried that he will be honest and admit his connection to Reshbihari, the person who orchestrated the assassination attempt. But Puran Singh struggled against his conscience and lied in court after being convinced by his friends and family. As a result, another person Shri Amir Chand received the death penalty while Puran Singh was spared. Puran Singh was devastated by Amir Chand's passing and he addressed an open letter to Sir John Simon in response against the establishment of the Simon Commission in 1928. He was very vocal in his criticism of it and his full letter can be seen here .
Puran Singh was set free following his arrest on return to India (due to his speeches in Japan), and was immediately taken to Lahore by his parents, who paid hefty bail money and assurances on his behalf. On March 5, 1904, just six months after his homecoming, he wed Maya Devi, upon the wishes of his dying sister . Maya Devi was a grounding support in his life. His dedication to her in his poem 'Seven Baskets of Prose' reads: "To my companion of these flying days on this earth, Shrimati Maya Devi Ji, in grateful acknowledgement of the priceless love she offered and with which she soothed me in my troubles on the life's path by her daily crucifixion for me in the noble silence of her soul." 
Puran Singh had 1 daughter and 3 sons. Gagri was the name of his daughter, who was born in March of 1905. Additionally, they had three sons : Madanmohan Singh (1 August, 1907), Satwant Singh (1 January, 1910) and Raminder Singh (15 September, 1913).
First Research Paper & Scientific Achievements
Puran Singh wrote his first paper and gave a discussion on "The Future of Cutch and Katha Manufacture" at the Punjab Forest Conference in Lahore in January 1908, and it was published in the Indian Forester Bulletin in Volume 35, Issue 2, February 1909. He went into great detail about the drawbacks of traditional methods (and that proposed by Dr. Warth - a prominent chemist in the west) for producing cutch or dark catechu, also known as Katha. Puran Singh proposed innovative methods that could be used in the manufacturing to maximise profit with minimal waste . Dr. Leather, an agricultural chemist working for the Indian government, got in touch with Puran Singh to adopt Dr. Warth's discovery to improve it and set out to put it to the test. Puran Singh then conducted a rigorous analysis of both recommendations in his 4th subsequent paper and came to the conclusion that Dr. Leathers' approach is better suited for the production of katha. In addition, Puran Singh tried using methyl alcohol as a solvent rather than water to extract catechin. He explained the novel combined ways of producing Cutch and Katha in his study paper's conclusion, as well as the combined use of water and wood spirit in Cutch production .
Puran Singh published his second paper on the utilisation of Khair Forests in Eastern Bengal and Assam (1908).
His third paper was on the manufacture of Ngai Camphor (1909).
Other notable papers include:
- Manufacture of Pure Shellac (1909) 
- Chemical investigation of the constituents of Burmese Varnish (1909)
- Tanning materials and the manufacture of tanning extracts in India, presented at the All-India Industrial Conference in December 1909
- Bleaching of some Indian coloured woods (1909)
- Analytical Constants of pure shellac, lac, resin & lac wax (1910)
Overall, Puran Singh wrote over 53 piece of novel scientific works, including papers, notes, conference articles and books (See end of this page for the full list). His last published scientific work is a note on the 'Preparation of Turpentine, Rosin and Gum from Boswellia serrata (Roxb.) gum-oleo-resin. This was co-authored by R.S Pearson and was published in the Indian Forest Records (1919).
While employed as a sugar chemist in the Sardar Nagar Sugar factory run by Sri Sundar Singh Majithia during 1923–24, it is believed that he received a patent for a brand new technique for decolorizing raw sugar without the use of bone charcoal .
Diverse Career & Employment Positions
Puran Singh was a multipotentialite and was not afraid to speak his mind. He took many positions and career options, as his work ethics and principles often contradicted with imperialist & capitalist mindsets of his peers.
To being with, in Lahore's Anarkali Bazar, Puran Singh started a distillation company to pay off his parents' debts, which they had racked up as a result of borrowing money from the neighbourhood to pay for his son's education. He produced essential oils of geranium and citrus with great success, using locally accessible tools like clay pots and metallic vessels. However, it failed as a result of his partners' conflicts about money which made Puran Singh furious and he broke the distillation equipment before storming away from the shop in anger .
Following this failure in business, Puran Singh took up work in the Victoria Diamond Jubilee Hindu Technical Institute was chosen as its principal in 1904. He retired in 1906 after two years of service to the college .
When the Imperial Forest Research Institute was established by the government in 1907, Puran Singh was chosen as chemical advisor. He began his career as a chemist in 1908 at the Dehradun-based Forest Research Institute's (FRI) department of chemistry for forest products . He was the only person of Indian origin to be posted in one of the six research positions in FRI. He also led the chemistry division from 1906 - 1919, which is a 13-year long term . His studies were greatly facilitated by the upgraded facilities, which also allowed him to publish 53 research papers in the Indian Forester and Forest Bulletin. He concentrated on isolating and analysing the essential oils extracted from oils of camphor, geranium, wintergreen, sandalwood, and khus.
Puran Singh also created a novel extraction condenser for camphor oil. He vigorously advocated for the industrialisation of the extraction of essential oils and their application in the medical field. He recommended enhancing the methods for extracting, distilling, and clarifying turpentine oil. He concentrated all of his efforts on advancing the essential oil industry after leaving FRI .
At the Indian Forest Research Institute, Dehradun, an English chemist was hired directly in 1916, and Puran Singh was asked to help him and operate under his direction. When he discovered that the Englishman was not up to par with his abilities and had only been appointed because of his white privilege, he was furious. However, he was asked to help him. In response to this display of disdain, Puran Singh resigned.
He was employed by the Maharaja of Gwalior, Madhav Rao Scindia, to create eucalyptus and rosha grass essential oils that were later shipped to England. He would only agree to work for him in exchange for a deposit of two lakh rupees and 25,000 rupees for the education of his children. He was given access to a vehicle,a bungalow, and a chauffeur. After a disagreement with Raja, he returned to Dehradun by the next train. The raja wrote him four letters to persuade him to return, but he didn't budge. In the end, the Raja paid a full one-year salary to Puran Singh .
Puran Singh was then employed by Sundar Singh Majithia during 1923–24 for purifying sugar and he then attempted another business opportunity for his own agricultural endeavour.
In 1926, Puran Singh was given 15 squares (Morabbas) of agricultural land on lease in the Sheikhupura district by the British Government to grow and export Rosha grass. But regrettably, he had to give up on this enterprise after his crops in Punjab were ruined by a flood in 1928 .
Literary Work as a Poet
Puran Singh experimented with fiction, poetry, prose, theatre, translation, critique, scientific, and religious essays. He was a trendsetter in Punjabi literature. He was known as the Punjab's Tagore. C.V. Raman, Tagore, and Iqbal were close friends of his.
He started a paper from Lahore, The Thundering Dawn, and edited it for a year. In 1906, he wrote a comprehensive introduction to his works, collected and published by Master Amir Chand . He published four Hindi novels in the span of six years (1912–1918). He also wrote biographies of Guru Nanak Dev ji and Guru Gobind Singh ji.
He was a particularly talented and prolific writer who could write equally well in Punjabi and English. Some of his literary works were published in London and some in India. The remaining unpublished works were later made public by Panjab University in the years following 1960.
His London published works include "The Sisters of the Spinning Wheel and Other Sikh Poems, Original and Translated” (1921), followed by “Unstrung Beads” (1923), and “The Temple Tulips” (1923), besides “Nargas: Songs of a Sikh” (1924), which included Punjabi poems written by Bhai Vir Singh. Next, he published The Story of Swami Rama: the Poet Monk of the Punjab (1924), which described the life of the first guru in prose. He also wrote “The Spirit of Oriental Poetry” (1926), in which he emphasised what true poetry should be.
His book, “The Book of the Ten Masters” (1926), introduced ten Sikh Gurus to his English readers . He also translated Tolstoy's Resurrection in a mere eighteen days and published it as “Moyan Di Jaag”—as his wife wrote in her book .
His autobiography, “On Paths of Life,” is a work of art. He reminisced about his childhood with such fondness and described his childhood spent in Pothohar. He talks about his closeness with his mother, her mother's religious outlook, and the plight of his sisters. He vividly tells us about his experiences during his Japan travels and all the hardships he faced while living there. He was awestruck by Japanese mannerisms and culture and took great joy in participating in them. He also wrote an essay, Walt Whitman and the Sikh Inspiration, in 1928. His other works include Prakasina: a Buddhist Princess, The Spirit Born People, which was published in three volumes by Panjab University on his birth-century .
Note: - There are several unrecognised & unreferenced works of Puran Singh in poetry, especially in Punjabi language, that is unknown to general readers.
