Although many artists refused to accept an African-American apprentice, in 1879 Tanner enrolled at the Pennsylvania Academy of the Fine Arts in Philadelphia, becoming the only black student.
His decision to attend the school came at an exciting time in the history of artistic institutional training.
 Art academies had long relied on tired notions of study devoted almost entirely to plaster cast studies and anatomy lectures.
This changed drastically with the addition of Thomas Eakins as "Professor of Drawing and Painting" to the Pennsylvania Academy.
Eakins encouraged new methods, such as study from live models, direct discussion of anatomy in male and female classes, and dissections of cadavers to further familiarity and understanding of the human body.
Eakins's progressive views and ability to excite and inspire his students would have a profound effect on Tanner.
The young artist proved to be one of Eakins' favorite students; two decades after Tanner left the Academy,  Eakins painted his portrait, making him one of a handful of students to be so honored.

At the Academy Tanner befriended artists with whom he kept in contact throughout the rest of his life, most notably Robert Henri, one of the founders of the Ashcan School.
During a relatively short time at the Academy, Tanner developed a thorough knowledge of anatomy and the skill to express his understanding of the weight and structure of the human figure on the canvas.
