Re: Monday, number 2
Let's see, Frank Bunker Gilbreth was a bricklayer at the turn of the Twentieth Century when he met and married Lillian Moller. They went on to have twelve children, (because they thought it would be "efficient.") Two of their children, Ernestine and Frank, Jr, (number three and number five, respectively), went on to write a pair of biographies on their family, along with a number of short stories with a similar theme. The titles were "Cheaper by the Dozen," and "Belles On Their Toes," both made into movies starring Myrna Loy.
To answer your questions at this time would be quite efficient, but not in the spirit of this forum. It is sufficient to say that they called it something quite different from what they call it today.
In listing the two people you mention, one must not ignore the contributions of Frank Gilbreth's partner (and wife) Lillian. An engineer in her own right, she continued his work after his death in 1924. The original design for the "Efficiency Kitchen" was hers, and today there is a substantial scholarship fund in her name available for women wishing to become engineers.
