     The teacher who did the most to encourage me was, as it happens, my aunt.She was Myrtle C.

Manigault, the wife of my mother's brother Bill.She taught me in second grade at allblack Sumner

School in Camden, New Jersey.

     During my childhood and youth, Aunt Myrtle encouraged me to develop every aspect of my

potential, without regard for what was considered practical or possible for black females.I liked to

sing; she listened to my voice and pronounced it good.I couldn't dance; she taught me the basic

dancing steps.She took me to the theatre-not just children's theatre but adult comedies and

dramas-and her faith that I could appreciate adult plays was not disappointed.

     My aunt also took down books from her extensive library and shared them with me.I had books

at home, but they were all serious classics.Even as a child I had a strong liking for humour, and I'll

never forget the joy of discovering Don Marquis's Archy & Mehitabel through her.

      Most important, perhaps, Aunt Myrtle provided my first opportunity to write for publication.A

writer herself for one of the black newspapers, she suggested my name to the editor as a "youth

columnist". My column, begun when I was fourteen, was supposed to cover teenage social

activities-and it did-but it also gave me the freedom to write on many other subjects as well as the habit

of gathering material, the discipline of meeting deadlines, and, after graduation from college six years

later, a solid collection of published material that carried my name and was my passport to a series of

writing jobs.

     Today Aunt Myrtle is still an enthusiastic supporter of her "favourite niece". Like a diamond, she has

reflected a bright, multifaceted (多面的) image of possibilities to every pupil who has crossed her path.
