David Sidney Bloch was born May 8, 1896, in New York City, the son of Samuel and Pauline (Maibrumm) Bloch. He had an older sister, Elsie, born in 1887, and an older brother, Alfred, born in 1890. His father, Samuel, was a German immigrant who made a very good living as a butcher (also the profession of David's grandfather Maibrumm, who shared their home with them in 1900). The family made their home on West 81st Street in Manhattan, and always employed at least 2 servants, usually a cook and a maid.
In 1915, 19 year old David was working as a stock clerk. In 1918 he enlisted in the Army as a 2nd Lieutenant, serving overseas in WWI from April 1918 through May 1919.
On August 27, 1937, David married Ellen Klara Louise Sorensen Wiig, a Danish immigrant who came to the United States with her mother in 1904 on the S.S. Hellig Olav. Her birth name was Sorensen, but she was raised by her step-father, Carl Wiig of Chicago, and she assumed his last name.
David and Ellen made their home in 1940 at 307 W. 106th Street in New York City; and later at 252 E. 61st Street.
David worked as a salesman in "silks and velvets", in 1942 working for the Vanetta Velvet Corporation.
In 1942, even at the age of 45, David was required to register for the draft during WWII.
David Bloch died aged 81 on January 29, 1981, at the Lenox Hill Hospital, and was buried on Hart Island.
