Albert Rathbone was a partner of the firm from 1893 to 1899. Rathbone, born in Albany in 1868, graduated from Williams College and Albany Law School. He joined the firm in 1893 which then became known as Tracey, Cooper & Rathbone.
Like Tracey, Rathbone was an expert in corporate law and finance. In 1899 he left the firm to relocate to New York City. In 1901 he became a partner in Joline, Larkin & Rathbone, and in the booming decade before World War I, helped organize and reorganize many major US corporations, including several railroads. After the war he was named by Woodrow Wilson as the Assistant Secretary of the US Treasury.
In 1920, he returned to his law practice at his old firm, which shortly thereafter became Rathbone, Perry Kelley and Drye with Rathbone as the senior partner. Under his leadership the firm became one of the most prestigious in the country.
Rathbone died in 1943 at the age of 75. He is buried in the family plot in Albany Rural Cemetery.
