Mary Lee Wheat's parents were Lillie Alves and Neil Claude Wheat. Her mother had been a school teacher before she married and her father held a variety of jobs from policeman to truck driver and mechanic, and finally the manager of a trucking firm. In fact Mary was part of an extended family since her father's brother had married her mother's sister and they had one child, a son who was one year older than Mary. Three of Mary's grandparents had been born in Nebraska, while the fourth had emigrated to Nebraska from Germany.
Mary's parents encouraged her to learn when she was young. They taught her history and Mary's father was asking her mental arithmetic questions when she was five. She attended high school in Hastings, Nebraska, in the class one year below her cousin. The subjects which she enjoyed most were mathematics, history and physics. When she was in her final year of study her father died from a heart attack. At this stage Wheat's mother took a job working in Hastings College cafeteria to help support the family and, after graduating from high school, Wheat became a student at Hastings College. It was in her second year that a new lecturer, Jim Standley, joined the mathematics staff at the College. Her talent for mathematics had already been recognised but it was Standley who suggested to Wheat that she go on to postgraduate work. It was something she had never considered before, but once it was suggested to her she found it an attractive idea.
Wheat graduated from Hastings College in 1959 having taken mathematics and physics as major subjects. She had been awarded a Fulbright fellowship to allow her to study in Germany so she went to Frankfurt to study at the J W Goethe Institute. Returning to the United States after a year, Wheat began graduate studies at the University of Kansas. She was awarded a Master's degree in 1962 and continued research for her doctorate supervised by William Scott. After submitting her thesis Radical Subcategories in 1964 she was awarded her Ph.D. Her studies were partially financed by fellowships from the National Science Foundation and partly by working as an assistant instructor at the University of Kansas. She was also employed as a physicist at the National Bureau of Standards each summer.
After graduating, she married Alfred Gray, also a mathematician, who she had met while at the University of Kansas. Her husband was appointed to the University of California at Berkeley while Mary Gray taught a course at Berkeley during the summer and then was appointed to the California State University at Hayward. In 1967 she published two papers, Radical subcategories and Abelian objects both of which were published in the Pacific Journal of Mathematics. In the following year Mary and her husband moved. He was appointed to the University of Maryland and she was appointed to the American University in Washington. They chose to live between the two sites to make sure neither had too long a journey to work. In 1970 she published an important book A radical approach to algebra. Edward Patterson writes that the book:-
... takes the idea of a radical as its main theme, to which it sticks closely throughout, whilst nevertheless describing many other significant ideas of modern algebra. ... The method of presentation in this book is to introduce ideas in basically an ascending order of technical complexity, which results in the material being arranged to a certain extent in the historical order of development. ... The book is well written and proofs are set out in a concise manner.
Gray has done much to support the role of women mathematicians. She published the article Women in mathematics in the American Mathematical Monthly in 1972. At the time she was president of the Association for Women in Mathematics, an organisation which she helped to found, holding the position from 1971 to 1973. It was a role which Gray undertook with determination. One of her first acts was to put pressure on the American Mathematical Society who she felt did not have nearly enough women on their committees or among the speakers at their conferences. She tackled the problem head on and, after carefully reading the by-laws of the American Mathematical Society, tried to attend one of the Council meetings of the Society. It was explained to her at the door that such meetings were not open for members to attend. Gray, who had read the by-laws, correctly explained that this was not specified but was told that members did not attend because of a gentleman's agreement. She then said, "I'm not a gentleman, I'm staying." Later Gray was elected to the Council and in 1976 was elected the second female vice president (the first was Charlotte Scott seventy years earlier). A good example of Gray's views is given in the article Gender and mathematics: mythology and misogyny which she published in 1996 as a chapter in the book Towards gender equity in mathematics education (Kluwer Acad. Publ., Dordrecht). Another article which deals with these issues is The Association for Women in Mathematics - a personal view which appears in the Mathematical Intelligencer 13 (4) (1991).
In addition to her mathematics, through the 1970s Gray studied law, receiving a law degree with distinction from Washington College of Law in 1979. Her training helped her fight more effectively for women's rights. Fasanelli writes :-
... she might easily be found in Bosnia, Chile, Israel or Rwanda. She might be found testifying before congressional committees on Capitol Hill or appearing as an expert witness in California courtrooms. Through her knowledge of law and statistics, and her attention to social justice, she has found many ways to use her professional training to help people around the world. ... She testified about income tax reform to the U.S. House Ways and Means Committee; on affirmative action at the Department of Labor; on pensions and insurance for five U.S. congressional committees as well as in eight states from Maine to Oregon. She has also testified on age discrimination, Social Security, pay equality, women and the military, retirement income security, the constitutional right to travel, and women in science.
Of the awards which Gray has received we mention two in particular. She was honoured by the Association for Women in Mathematics in 1991. The citation reads:-
It is especially fitting that Mary Gray be honored at the Twentieth Anniversary meeting of the Association for Women in Mathematics, since she is the one person most responsible for the existence of this organization; for years her name was virtually synonymous with Association for Women in Mathematics. She ran the organization almost single-handedly for its first two and a half years, serving as chair during that period and producing the Newsletter for the first four years.
During this same period, Mary was working to insure broader membership participation in the established mathematical societies. She worked to open American Mathematical Society Council meetings to observers, as provided in the bylaws, and to make common practice the nomination by petition for certain American Mathematical Society offices. In 1976, Mary became the second woman Vice President of the Society (nominated by petition) and the first in seventy years.
On an even broader front, Mary has been active on Committee W, the Committee on Women of the American Association of University Professors, serving as its chair from 1973 until 1978 and again since 1986. She served as President of Women's Equity Action Leagues from 1982 to 1988. Her concern for the rights of all humans is evidenced by her involvement with Amnesty International, currently as Treasurer and member of the Board of Directors of Amnesty International USA.
The second award which we mention is the 1994 Mentor Award for Lifetime Achievement from the American Association for the Advancement of Science. The award was given for :-
... the extraordinary number of women and underrepresented minorities she has affected in her career both directly and indirectly through the influence of her former students and the programs she has initiated and developed. Her twenty doctoral students include eleven women and five African American women.
