The Honorable Alexander Edward Ross (born February 1, 2310 in New Avalon, Reydovan Prime) is a fictional character created by Joshua Underwood in the Star Trek universe. Ross is portrayed by Sir Derek Jacobi, known for his dramatic roles in film and theater and for his distinctive speaking voice. When he was created in January 2006, he was portrayed by the late John Spencer, known for his portrayal of Leo McGarry on The West Wing. Underwood chose Spencer for this character both because of his admiration of his acting style and because of the "wise old man" personality that Spencer seemed to possess.
