Lithuanian Jewish family in
Goldingen in the
Courland Governorate in the
Russian Empire. He was the son of Martin Sass Eder and Dorina Kaiser, and was the youngest of their seven children. In 1851 Santiago Eder immigrated from Courland to
New York City where his older brother and most of his siblings already lived. He completed his education and after some work experience entered
Harvard Law School in 1858. In 1861 he moved to
San Francisco, and from there moved to the Colombian sea port of
Buenaventura where he worked as a lawyer and a commercial representative for
Panamanian trading firms when Panama was still part of Colombia. In 1864 he bought the
Manuelita sugar and coffee farm near the city of
Palmira in the
Cauca Valley of Colombia. He bought this farm at a public auction in
Cali from the father of leading Colombian novelist
Jorge Isaacs. In 1866 Eder became the
consul of the
United States in Buenaventura, as well as the vice-consul of
Chile. In 1867 he traveled to
London where he met and married Elizabeth 'Lizzie' Benjamin in the New Synagogue. In their marriage certificate, the name of don Santiago's father is given as 'Moses Eder'. From this marriage were born his children Henry, Charles, Luisa, Walter, Phanor, Fanny and Edith Eder. ==Industrial pioneer in Colombia==
