, as a practicing attorney, then returned to New York. While he maintained an attorney's office until 1884 he was more interested in pursuing an academic career at his alma mater, Columbia. A prize lectureship had been created in 1882. To be eligible a candidate had to be a graduate of Columbia, a member of the Academy of Political Science and read at least one paper before the academy. The three year appointment came with a $500 annual salary ($ in terms) and required the lecturer to give twenty lectures a year, based on original research, to the students of the School of Political Science. De Leon devoted his lectures to Latin American diplomacy and the interventions of European powers in South American affairs. He received his first term in 1883 and his second term in 1886. In 1889 he was not kept on. Some allege that the University officials denied him a promised full professorship because of his political activities, while other believe that his subject was too esoteric to be a permanent part of the curriculum. De Leon published no papers about Latin America during this period, but he did contribute an article to the debut issue of the Academy's ''

After a traditional Jewish wedding in Caracas the family moved to a Spanish speaking area of Manhattan, at 112 West 14th street where their first son, Solon De Leon would be born on September 2, 1883. By the mid to late 1880s the family was living on the

On April 29, 1887, Sarah Lobo De Leon died in childbirth while delivering stillborn twins; it was the same year that Grover had died. After this the De Leons left the Lower East Side and moved in with their housekeeper Mary Redden Maguire at 1487 Avenue A. In 1891, while on a speaking tour around the country for the SLP, De Leon found himself in Kansas when he learned that a planned speaking engagement in Lawrence had been canceled. He decided to head to

He arrived on April 23 and was hosted by a 26-year-old school teacher, Bertha Canary, who was the head of a local Bellamyite group, the Christian Socialist Club. Canary was familiar with De Leon, having read some of his articles in the Nationalist Club movement press, and the two apparently became infatuated with each other. She was a member of a Congregational Church and in 1892 they were married in South Norwalk, Connecticut. They had five children: Florence, Gertrude, Paul, Donald and Genseric.

De Leon was formally expelled from the Chicago IWW after calling proponents of that organization "slum proletarians". His Socialist Labor Party has remained influential, largely by keeping his ideas alive. De Leon died on May 11, 1914, of septic
