A stellar art program, not racial politics, had brought him to the so-called Castle on the Hill, then the Ivy League of public high schools locally and nationwide. And this bright young man simply wanted to register and get to class.
As Brown's impact resonated across America, students across the racial spectrum would find themselves called upon to help shoulder the burdens of a nation grappling with race in the classroom and larger society.
So Mr. Gill walked, past the equally youthful white faces of students who neither cheered nor jeered, but stared curiously at the transfer student from all-black Frederick Douglass High School. He walked that day with measured steps, gaze fixed straight ahead, his heart and head insisting he could do this, even though he was too young to fully comprehend that he was, indeed, striding into history.
Though nine other blacks helped integrate City, though the school had students of other ethnicities, Mr. Gill would become what one newspaper termed "the first of his race to graduate."
In a sense, the Greenville, Miss., native had been preparing for this moment all of his life. Academically and artistically talented, he was the first born of college-educated parents and entrepreneurial grandparents who owned several businesses. Lessons in racial pride, scholarship, civic duty, ambition and courage were as commonplace as grits for breakfast.
In the Greenville of his youth, race loomed omnipresent: "white" and "colored" signs, the balcony of the local movie theater where blacks had to sit, the many places they could not go. Still, it was a world Mr. Gill remembers fondly as "a beautiful town, the Queen City of the Delta."
He and his playmates - just as often white as black, he says - fished and swam in the Mississippi, romped in the woods. No name-calling, he says. No adults around to race-bait and keep boys from being boys.
"Being born in the South, you knew who you were and where you belonged," Mr. Gill explains, referencing not so much skin color but support systems. "There was family and community. It seemed like everybody knew you. You knew where to go for help."
When he was 8, the family relocated to Baltimore after his father, a professor with a doctorate in political science, accepted a teaching position at Morgan College. They would settle in Hoes Heights, a black enclave built in the 1930s near what is today 40th Street near Roland Avenue.
Ensconced in this tight-knit black community, Mr. Gill experienced love and support similar to that he'd felt back in Mississippi, the place he returned each summer. The feeling was reinforced at Coppin Demonstration School.
And this foundation provided Mr. Gill with the fortitude and academic tools he would need to survive at City, where many teachers treated him coldly, and his classmates were not unkind but often ambivalent.
City alumni Sidney Krome and Lewis Noonberg recall how at nearby Mervo, students planned protest marches, hoping City boys would join their quest to keep schools white.
"Robert Hammerman [then a young attorney and now a retired judge of the Baltimore City Circuit Court] visited me, and asked what I was going to do," recalls Mr. Noonberg, who was senior class president. "Really, I hadn't thought about it." But thanks to a telephone chain Mr. Noonberg initiated, it's believed that few if any City students joined that hateful march.
Yet the City students could not prevent other injustices, or the isolation often felt by Mr. Gill, who lettered in track and earned good grades.
He formed few if any deep friendships at City. Instead, he maintained strong ties with former classmates from grade school and Douglass High - even inviting several buddies and their dates to City's senior week activities.
"Gill and his friends attended all of the graduation events save one," notes the June 11, 1955, Afro-American. "He boycotted the dance in the Dixie Ballroom at the Gwynn Oak Park, when a last-minute restriction was added: He could attend, but couldn't use the park's concessions with other students."
Another slight came hours after the graduation. When he and white classmates went to a local eatery for breakfast, he was refused service. Eventually, the group found a place where everyone could break bread together.
Despite such incidents, peace, not bitterness, today describes this 66-year-old husband and father who earned degrees from Morgan State and Syracuse University, the latter a doctorate in educational communications.
Inducted into City's Hall of Fame in 1997, the semi-retired professor, administrator, artist, veteran, author and consultant has spent his career touching the lives of thousands of students, many labeled high-risk.
The Brown decision "had to be made if the country was to live up to its principles of democracy," Mr. Gill says. Yet he believes society still has "a long way to go" toward ensuring that children of color and impoverished backgrounds receive a quality education, especially in light of what he dubs the "re-segregation" of schools.
He holds blacks and whites equally culpable. Far too many whites quietly hold the view that they're "sharing our schools," when the institutions are meant for everyone, says Mr. Gill. And he notes that blacks, particularly the middle and upper classes, have largely abandoned inner-city schools and neighborhoods for suburban dreams.
"They say it takes a village to raise a child, but that was when everyone lived in the village, or at least came back to visit," he says. "You can leave, but you must come back to help your people. If someone can invest on Wall Street, why not buy and transform a city block, or invest in our schools?"
Still teaching, Mr. Gill continues to do his part at the Woodbourne Center in Northeast Baltimore. Along with art lessons, he imparts values about making an honest living, building a family and helping those who are less fortunate as keys to success.
Just as Brown helped change his life, Mr. Gill wants his students to grasp how a prime education, the bonds of family and community and the support of a nation bent on doing right can profoundly influence their lives, too. He wants them to take advantage of the sacrifices he and others have made, to keep climbing. Mr. Gill wants them to know his own climb up a steep hill has been well worth the trek.
