Born on 11 February 1868, Khan descended from a line of physicians who had come to India during the reign of Mughal EmperorBabar. His family were all Unani doctors and "a king without a crown". Hakim Ajmal Khan, like his father, was reputed to effect miraculous cures and to have possessed a "magical" medicine chest, the secrets of which were known to him alone. Such was his medical acumen that it is said that he could diagnose any illness by just looking at a person's face. Hakim Ajmal Khan charged Rs. 1000 per day for an out-of-town visit but if the patient came to Delhi, he was treated free, regardless of his position in society. Khan proved to be the most outstanding and multifaceted personality of his era with matchless contributions to the causes of Indian independence, national integration and communal harmony. He took great interest in the expansion and development of the native system of Unani medicine and to that end built three important institutions, the Central College in Delhi, the Hindustani Dawakhana and the Ayurvedic and Unani Tibbia College better known as Tibbia College, Delhi, which expanded research and practice in the field and saved the Unani System of Medicine from extinction in India. His untiring efforts in this field infused a new force and life into an otherwise decaying Unani medical system under British rule. Khan proposed the absorption of Western concepts within the Unani system, a view diametrically opposite to that adopted by physicians of the Lucknow school who wanted to maintain the system's purity. Hakim Ajmal Khan also recognised the talents of chemist Dr. Salimuzzaman Siddiqui, whose subsequent research into important medicinal plants used in the field gave Unani medicine a new direction. As one of its founders, Khan was elected first chancellor of the Jamia Milia Islamia University on 22 November 1920, holding the position until his death in 1927. During this period he oversaw the University's move to Delhi from Aligarh and helped it to overcome various crises, including financial ones, when he carried out extensive fund raising and often bailed it out using his own money.
After the partition of India, Khan's grandson Hakim Muhammad Nabi Khan moved to Pakistan. Hakim Nabi had learnt Tibb from his grandfather and opened 'Dawakhana Hakim Ajmal Khan' in Lahore which has branches throughout Pakistan. The motto of the Ajmal Khan family is Azal-ul-Allah-Khudatulmal, which means that the best way to keep oneself busy is by serving humanity.
Quotes
"The spirit of non-cooperation pervades throughout the country and there is no true Indian heart even in the remotest corner of this great country which is not filled with the spirit of cheerful suffering and sacrifice to attain Swaraj and see the Punjab and the Khilafat wrongs redressed." – From the Presidential Address, Indian National Congress, 1921 Session, Ahmedabad.
