Biography Timeline


Upon graduating from Columbia College in 1911, Stewart accepted a three-year position with the United Presbyterian Church teaching botany and zoology at Gordon College (Pakistan), in Rawalpindi (then in India). After spending from September, 1911 until July, 1914, in that position, he returned to the United States and in the fall of 1914 began graduate studies at Columbia. In 1916 he completed his Ph.D. and married fellow-Columbia graduate student Isabelle Caroline Darrow, sister of botanist George M. Darrow. That fall he returned to Gordon College, where he served as Professor in Botany (1917–1960), and Principal of Gordon College (1934–1954).


In September 1916, Stewart married Isabelle Caroline Darrow (1888-1953) at the bride's home in Middlebury, Vermont. Darrow, also born in Hebron, New York, graduated from Middlebury College in 1911, and then spent 1911-14 teaching science in a United Presbyterian Church position at Anatolia College in Merzifon. She was the sister of botanist George M. Darrow. The couple met studying for graduate degrees in science at Columbia in 1915, both wishing to return to teaching abroad. They had two daughters: Jean Macmillan Stewart Andrews (1919–1970), born in Sialkot, and Ellen Reid Stewart Daniels (1921–1998), born at Jhelum, and six grandchildren and six great grandchildren. After the death of Stewart's first wife, in 1954 he married Winifred Hladia Porter (1896–1984). He died in 1993 in Duarte, California.


In recognition of his services to educational and botanical work, Stewart was awarded the Kaisar-i-Hind Medal in 1938, and the Sitara-e-Imtiaz (Star of Distinction) in 1961. He was recognized as a Member of the American Association for Advancement of Sciences in 1984, and as a foreign member Pakistan Academy of Sciences in 1983.


After retiring from Gordon College, in 1960 Stewart moved back to the United States. He took a position as Research Associate (1960–1981) at the University of Michigan Herbarium with over 30,000 plant specimens that he had collected in India, Kashmir, Iran, etc.

At that time the flora of India and Western Himalayas was not well known. Stewart embarked on plant collection trips, often on his bicycle, as far as Kashmir and into Western Tibet. He continued to collect plants every summer (1912–1959) without any financial support. In 1960, when Dr. Stewart retired at the age of 70, he gave his collection of over 50,000 plant specimens, now called the Stewart Collection, to Professor E. Nasir at Gordon College (Rawalpindi). The Stewart Collection has been deposited in the National Herbarium of the government of Pakistan at Islamabad, leaving a very rich heritage for the students of plant sciences.


In 1982, at the age of 91, Stewart wrote a sort of memoir, Flora of Pakistan: History and Exploration of Plants in Pakistan and Adjoining Areas, in which he wrote:


Dr. Stewart returned to Pakistan in 1990 to visit Gordon College and make a presentation at the International Symposium on Plant life of South Asia. The symposium was organized at the Department of Botany, University of Karachi, to commemorate the centenary of Dr. Stewart. The participation of Stewart is indicative of his interest of plant sciences and his love for Pakistan.
