The Career of a Structural Chemist: A Retrospective

Bobby L. Barnett
The Procter & Gamble Company

A structural chemist, frequently an X-ray crystallographer, has an intense interest in the shapes of molecules and what role these molecules play in nature. X-ray crystallography is a discovery science and the crystallographer is usually the first person to visualize the 3D structure of a molecule. I would like to take this opportunity to describe some of the more interesting structural problems that I have encountered.

Before I came to P&G, I was fortunate to work in several great institutions and work with some really good chemists. Several examples will be described that illustrate what attracted me to crystallography and structural chemistry, like seeing catalytic intermediates and the first sodium anion!

At P&G, there were lots of interesting structures, but the most exciting was a series of structures to elucidate how bisphosponates work, especially as bone imaging agents. While I was trying to convince more chemists to use 3D structural information, I started the molecular modeling group. In an effort to demonstrate the power of modeling, I was fortunate to participate in the beginning of P&G’s protein engineering group and worked on designing better detergent enzymes. In the last few years, I have gone back to crystallography and am participating in the ultimate use of structure in structure-based drug design. Examples of each of these eras will be described.

About the Speaker

Dr. Barnett received his B.S. and Ph.D. degrees in Chemistry in 1967 and 1970 respectively from the University of Texas, Austin. Armed with newly developed skills in crystallography, he continued his interest in organometallic chemistry with a postdoctoral position at the Max Planck Institute for Kohlenforshung, West Germany. After 2 1/2 years he returned to the states to be Departmental Crystallographer at Michigan State University. In 1974, he came to the Procter and Gamble Company, where he is currently employed. His initial assignment was in leading the efforts in crystallography and structural chemistry. After a short stint in the Corporate Microscopy laboratory, he introduced molecular modeling into P&G. As an initial project in molecular modeling, he helped build a protein engineering group focused on detergent enzymes. Currently he is involved in structure-based drug design for P&G Pharmaceuticals, using protein crystallography as the major tool. On the side, Bobby is an Adjunct Professor in the UC Chemistry Department and teaches a course every other year in Molecular Modeling.

He has been active in the local ACS section and began serving as Dinner Reservations Chairman (1975-1976). He also has held positions of Secretary (1976-77); Alternate Councilor (1979-1981); Treasurer (1984-85); Computational Chemistry Discussion Group Chairman (1986-89); First-Vice Chairman (1989-1990); Chairman (1990-1991); Trustee (1991-1994).

"The Challenges for Women—and Men—Chemists in the New Millennium"

A special Guest Speaker
Madeleine Jacobs, Editor-in-Chief
Chemical and Engineering News

Ms. Madeleine Jacobs will review data for the past three decades concerning the progress of women chemists, discuss the reasons that are usually given to explain the data, and describe a plan of action for women—and men—chemists in the new millennium. Among the questions she will address are: How much has changed for women chemists in the past three decades? How much has the salary gap between men and women been narrowed? How much progress has been made in breaking through the glass ceiling at universities and in corporate boardrooms? Can women chemists, especially those with children, really balance a personal life with a professional life? Are things really better? And what are the prospects for the new millennium? Is it business as usual? What can each of us do to make a difference? (see page 5 for biography)

About our Guest Speaker

Madeleine Jacobs is the first woman to be appointed editor (and editor-in-chief) of Chemical & Engineering News magazine, the weekly newsmagazine of the chemical world published by the American Chemical Society for its members and other interested professionals. The magazine, with its staff of 41 people in seven news bureaus around the world, celebrated its 75th anniversary in 1998. The current audited circulation is about 150,000. She came to this position by a rather circuitous route. Jacobs majored in chemistry at George Washington University and graduated with a B.S. in chemistry with honors and distinction (Phi Beta Kappa in her junior year) in 1968. Although accepted by Stanford University to pursue a doctorate in chemistry, Jacobs stayed in Washington because of pressing family matters. Instead, she carried out graduate work in organic chemistry for a year at the University of Maryland before joining the staff of C&EN in 1969. There, she was an assistant editor and writer both in the Washington, D.C., office of C&EN and on the West Coast, where she covered 10 western states. She worked at C&EN for three years.

In 1972, she worked at the National Institute of Allergy and Infectious Diseases as a writer and editor. In 1974, she joined the staff at the National Bureau of Standards (now NIST) where she rose to the position of chief of media liaison and general publications. In 1979, she joined the Smithsonian Institution as the chief science writer, and was soon promoted to assistant director and then director of the Office of Public Affairs. She returned to C&EN in 1993 as managing editor. She was appointed editor in April 1995 and assumed her new position in July 1995.

A native of Washington, D.C., Jacobs has been married to an artist for 26 years and has a stepson, a daughter-in-law, and two grandchildren, Matthew Jr., 14, and John, 9. Her hobbies include cooking, photography, swimming, weight lifting, gardening, and writing poetry.

From the Chair

Congratulations to Bobby Barnett of the Procter & Gamble Company for being named the recipient of the 1999 Cincinnati Chemist of the Year Award. Bobby will receive the award at this month’s meeting at the Procter and Gamble Health Care Research Center in Mason, Ohio and he will give the after-dinner address. We will also be honoring Ms. Lori Bacca, who will receive the Research Associate of the Year Award. Congratulations to both of our awardees.

In addition to the Chemist of the Year award we are also honored to have as our guest Madeleine Jacobs, Editor-in-Chief of C&E News. Ms. Jacobs will address the section members before dinner and the title of her talk is "The Challenges for Women—and Men—Chemists in the New Millennium".

This is the second year we will be having our February meeting at this site and we are very grateful to P&G for once again hosting one of our meetings. Please join us on February 24th.

Another item of business to be addressed is our annual election of officers for the section. The nominations committee is now in the process of selecting candidates. Please submit suggestions or nominations to Bill Oliver. Feel free to nominate yourself. Bill can be contacted at NKU via phone (606-572-5409), email ( or snail mail (Bill Oliver, Department of Chemistry, Northern Kentucky University, Highland Heights, KY 41099)

Plans for the regional meeting, CMACS 2000, are proceeding well and the pace is now picking up with only a little more than one year to go. The Planning Committee is still in need of additional help and volunteers are always welcome. Specific areas of need are committee chairs for the Student Affiliate Program and the ACS Clearing House. The Publicity and Printing Committee also is in need of additional members. Contact Ray D’Alonzo (513-626-1977; ) if you are interested
