Yes it is the Raymond Brooks I'm seeking information about. Interesting though that the 1880 census says the father was born in Ohio, while the 1900 and 1910 have the father born in Connecticut.
If you are interested in R.B., some Katanga information is at:
He was a listed member of AIME from 1905-1913, lapsed and the rejoined to become NY section AIME Vice-Chair in the early 1930s. He was the Institute's [AIME] representative to the NY Museum of Science and Industry in 1932-1933
His secretary embezzled from him in 1930; Norwalk Hour - Dec. 17, 1930 Helen Delaney, 28, and former secretary to Raymond Brooks, wealthy mining engineer, was held for a grand jury today on allegations that she appropriated between $30,000 and $60,000 of the engineer's funds.
Mrs. Laura R. Brooks of Brookdale, Conn, the engineer's wife, [2nd ??? as Marguerite named in 1910] brought the specific charge of forgery, asserting that Miss Delaney raised a $79 check, erased the name of the payee and inserted her own. Miss Delaney was held first in $5,000 bail, then $10,000. Today her bail was increased to $25,000.
Apparently she married a 'scammer, George M. Pynchon: One Mrs. Helen Delany Pynchon made the news in 1931. It was reported that she was saved from a jail term by the beneficence of her former employer, mining engineer Raymond Brooks, when she was convicted of robbing him of $45,000. Subsequently the George M. Pynchon estate was sold and, no end to ignominy, the estate’s furniture sold at public auction. Some reversal–from contemplating the world’s electric power needs, to having the furniture sold at auction.
Is the passport application public, an image available?
