Dr. M. Bonner Denton of the University of Arizona will deliver this year's James and Jeanette Neckers Lecture in Chemistry at Hope College on Friday, April 11, at 4 p.m. in room 102 of VanderWerf Hall.

He will present "Advances in the Application of Array Detectors for Improved Chemical Analysis." The public is invited, and admission is free.

Denton is a professor in the Department of Chemistry and the Department of Geosciences at the University of Arizona, where he has been a member of the faculty since 1971. His work on array detection technologies has won honors including, most recently, the award in Spectrochemical Analysis from the American Chemical Society.

The James and Jeanette Neckers Lectureship and Student Assistance Fund through which he is speaking was established in 1984 by Dr. James W. and Jeanette Hoffman Neckers, members of the college's Class of 1923, to support annual lectureships in chemistry. Through additional gifts from Dr. Neckers, the fund has been expanded to include student summer research stipends and student scholarships.

Jeanette Neckers died on June 10, 1992. James Neckers, who lives in Carbondale, Ill., was chairman of the Department of Chemistry at Southern Illinois University at Carbondale for 37 of his 40 years at the university. Under his leadership, the department grew from a three-year offering in chemistry to granting the doctorate; the faculty grew from three to 23.
