In memoriam of the late Professor Giovanni Arrighi (1937-2009), this essay reflects on his contribution to graduate mentoring based on the author’s personal experience. The idea that graduate students are the young scholars that collaborate with not-so-young scholars (professors) was the founding philosophy of graduate instruction in the Department of Sociology at SUNY-Binghamton. Professor Arrighi continued this tradition and mentored graduate students by embracing them into the extended Arrighi family. He treated students with respect and involved them into research activities as collaborators and co-authors. He acknowledged that he received academic stimulation from his student, and inspired graduate students through critical yet encouraging comments. With anecdotes from Binghamton days, the essay reports that Professor Arrighi continues to live in the mind, heart, and practice of those who received his mentoring.
