In this guide, 16 historical and contemporary black scientists and engineers are highlighted as role models. Four scientists are represented in each of four technical fields: life sciences (Ernest E. Just; Harvey M. Pickrum; George W. Carver; Patricia S. Cowings); physical science (George R. Carruthers; Percy L. Julian; Walter E. Massey; Warren M. Washington); mathematics and computer science (Fern Y. Hunt; David H. Blackwell; Marc R. Hannah; Benjamin Banneker); and engineering (Lewis H. Latimer; Norman R. Bliss; Christine M. Darden; Raphael C. Lee). Backgrounds of the men and women described include academia, industry, and government. The biographies include information about the scientists' educational background, professional achievements, and attitude towards their work; they also tell how these "black achievers" overcame tough challenges, highlighting qualities such as family background, determination, curiosity, and love of their chosen field, and other interests. Following each set of biographies is a career path chart for the technical area represented and each of these charts present information needed in planning for a career in science. As an aid in understanding the chronological ordering of these "black achievers" a reproducible timeline has been included, beginning with Benjamin Banneker (b.1731) and progressing to the present. Resource listings for professional organizations, publications dealing with careers, and publications used in producing this booklet are supplied. (KR)
