Abstract
The iron abundance in the helium star HD 144941 has been measured
from ultraviolet Fe III lines. It is
![[FORMULA]](img1.gif)
dex below solar and confirms the low metallicity
(![[FORMULA]](img2.gif)
) previously determined from measurements of CNO
and other light elements. The result is important because the low CNO
metallicity must be reflected in the iron-group elements in order to
explain why HD 144941 does not show pulsations.
