William Horwitz (1918-September 27, 2006 Olney, Maryland) was an analytical chemist who is notable for formulating a description of the relationship between the variability of chemical measurements and the concentration of the analyte. This relationship, called the Horwitz curve applies only to the between-laboratory variability of measurements.
Horwitz worked for the U.S. Food and Drug Administration (FDA) for 57 years until his retirement in 2000 and was head of the Association of Official Analytical Chemists for 24 years.
The Horwitz curve is "one of the most intriguing relationships in modern analtyical chemistry"; it is related to the Variance-to-mean ratio.
Famous quotes containing the word william:
“We agree fully that the mother and unborn child demand special consideration. But so does the soldier and the man maimed in industry. Industrial conditions that are suitable for a stalwart, young, unmarried woman are certainly not equally suitable to the pregnant woman or the mother of young children. Yet “welfare” laws apply to all women alike. Such blanket legislation is as absurd as fixing industrial conditions for men on a basis of their all being wounded soldiers would be.”
