“Her colouring is fair, the quality of her organization fine. There is, if anything, more sensitiveness than endurance ; more activity than absolute strength ; more quickness and vivacity than actual staying power or real physical vigour. At the same time, she has considerable intensity and “go,” and is not likely to give in unless absolutely obliged.”
—Author R. Dimsdale Stocker, on the physiognomy of Ellen Beach Yaw, American soprano, in The human face as expressive of character & disposition (1900), recently digitized from the National Portrait Gallery branch of the Smithsonian Libraries.
Yes, intensity and “go,” for sure.
