Isador Sobel (August 28, 1858 – October 25, 1939) was a Jewish-American lawyer from Pennsylvania.

During that time, he also worked as a clerk in a department store Niagara Falls, New York, and twice entered the mercantile business himself (once in Erie and once in Clarendon, Pennsylvania).

He purchased land in Vero Beach, Florida, in 1925 and maintained a real estate office there with his son Amos Sobel from 1925 to 1926.

In 1896, he served as chairman of the executive committee which was in charge of the campaign in Erie County, was the Republican candidate for mayor, and was the 1896 presidential elector for William McKinley.

[4] Early in Sobel's life, he wrote the weekly Jewish news of Erie for The American Israelite.

In 1906, he organized the Erie Lodge of the Independent Order of B'nai B'rith (which was later named after him) and served as its first president (an office he held for the rest of his life).

He was a member of the Pennsylvania Bar Association, the Freemasons, the Shriners, the Odd Fellows,[6] the American Jewish Historical Society, the Jewish Publication Society, and the Knights of Pythias.

Their children were Jeffrey Mortimer, Norman Tyler, and Sidney Amos.
