In Memoriam: Ben Barres

Ben Barres, professor of neurobiology at Stanford University and member of the editorial board for over 15 years, passed away on December 27, 2017, after a lengthy battle with pancreatic cancer. Ben left an indelible mark on the scientific community as a scientist, an advocate for equality, and an unbelievably supportive mentor. As a scientist his creative approaches led him to remarkable discoveries about the importance of glial cells in the brain, and his passion elevated these cells from the "other cells in the brain" to a significant place in the consciousness of neurobiology. As an advocate, he fought for equal treatment irrespective of gender identity, sexual orientation, race, or ethnicity, and was an inspiring supporter of junior scientists. As a mentor, he provided a creative and vibrant atmosphere for his trainees to pursue research and the never-ending support for them to flourish as independent scientists. As his former trainees, we would like to give our thoughts on Ben, and the deep impressions that he left on everyone he interacted with.
