The suspect, who was in custody by noon, opened fire inside the Tree of Life Synagogue in the city's Squirrel Hill neighbourhood, according to The Associated Press.
They were professors and accountants, dentists and doctors serving their local community.
A day after the shooting at a Pittsburgh synagogue that left 11 dead, officials released the names of the victims. The oldest of them was 97. The youngest was 54. They included a pair of brothers and a husband and wife.
Said Stephen Cohen, co-president of New Light Congregation: "The loss is incalculable."
CECIL AND DAVID ROSENTHAL
Cecil and David Rosenthal went through life together with help from a disability-services organisation. And an important part of the brothers' lives was the Tree of Life synagogue, where they never missed a Saturday's services, people who knew them say.
"If they were here, they would tell you that is where they were supposed to be," Chris Schopf, a vice-president of the organisation Achieva, said in a statement.
Achieva provides help with daily living, employment and other needs, and the organisation had worked for years with Cecil, 59, and David, 54, who were among the 11 killed in the deadly shooting.
They lived semi-independently, and Cecil was a person who was up for all sorts of activities: a concert, lunch at Eat 'n Park — a regional restaurant chain — even a trip to the Duquesne University dining hall, recalls David DeFelice, a Duquesne senior who was paired with him in a buddies programme.
"He was a very gregarious person — loved being social, loved people. ... You could put him any situation, and he'd make it work," chatting about the weather or asking students about their parents and talking about his own, says DeFelice.
And when DeFelice recognised Hebrew letters on Cecil's calendar, the elder man was delighted to learn that his buddy was also Jewish and soon invited him to Tree of Life.
DeFelice joined him on a couple of occasions and could see that Cecil cherished his faith and the sense of community he found at temple.
Emeritus Rabbi Alvin Berkun saw that, too, in Cecil and David.
"They really found a home at the synagogue, and people reciprocated," he said.
Cecil carried a photo in his wallet of David, whom Schopf remembers as a man with "such a gentle spirit."
"Together, they looked out for each other," she said. "Most of all, they were kind, good people with a strong faith and respect for everyone around."
The two left an impression on state Congressman David Frankel, who sometimes attends services at Tree of Life and whose chief of staff is the Rosenthals' sister. "They were very sweet, gentle, caring men," Frankel said. "... I know that this community will really mourn their loss because they were such special people."

MELVIN WAX
Melvin Wax was the first to arrive at New Light Congregation in Pittsburgh's Squirrel Hill neighbourhood — and the last to leave.
Fellow members of the congregation, which rented space in the lower level of the Tree of Life Synagogue, say Wax was a kind man and a pillar of the congregation, filling just about every role except cantor.
Myron Snider spoke late Saturday about his friend who would stay late to tell jokes with him.
He said "Mel," a retired accountant in his 80s, was unfailingly generous.
"He was such a kind, kind person," said Snider, chairman of the congregation's cemetery committee. "When my daughters were younger, they would go to him, and he would help them with their federal income tax every year. Never charged them.
"He and I used to, at the end of services, try to tell a joke or two to each other. Most of the time they were clean jokes. Most of the time. I won't say all the time. But most of the time."
New Light moved to the Tree of Life building about a year ago, when the congregation of about 100 mostly older members could no longer afford its own space, said administrative assistant Marilyn Honigsberg.
She said Wax, who lost his wife Sandra in 2016, was always there when services began at 9.45 am.
"I know a few of the people who are always there that early, and he is one of them," she said.
Snider said: "If somebody didn't come that was supposed to lead services, he could lead the services and do everything. He knew how to do everything at the synagogue. He was really a very learned person."
They went to the same college, the same medical school and even had the same residency at UPMC a few years apart.
"He is one of the finest people I've ever met. We've been in practice together for 30 years and friends longer than that," Ciesielka said.
"His patients are going to miss him terribly. His family is going to miss him terribly and I am going to miss him. He was just one of the kindest, finest people."
Former Allegheny County Deputy District Attorney Law Claus remembered Rabinowitz, 66, as more than a physician for him and his family for the last three decades.
"He was truly a trusted confidant and healer," he wrote in an email to his former co-workers. "Dr Jerry Rabinowitz ... could always be counted upon to provide sage advice whenever he was consulted on medical matters, usually providing that advice with a touch of genuine humour. He had a truly uplifting demeanour, and as a practicing physician he was among the very best."
Rabinowitz, a family practitioner at UPMC Shadyside, was remembered by UPMC as one of its "kindest physicians." The hospital said in a statement that "the UPMC family, in particular UPMC Shadyside, cannot even begin to express the sadness and grief we feel over the loss."
Joyce Fienberg and her late husband, Stephen, were intellectual power houses, but those who knew them say they were the kind of people who used that intellect to help others.
Fienberg was among the 11 victims of a gunman who entered the Tree of Life Synagogue in Pittsburgh and opened fire.
The 74-year-old spent most of her career at the University of Pittsburgh's Learning Research and Development Centre, retiring in 2008 from her job as a researcher looking at learning in the classroom and in museums.
She worked on several projects including studying the practices of highly effective teachers.
Dr Gaea Leinhardt, who was Fienberg's research partner for decades, said she is devastated by the murder of her colleague and friend.
"Joyce was a magnificent, generous, caring, and profoundly thoughtful human being," she said.
Stephen, who died in 2016 after a battle with cancer, was a renowned professor of statistics and social science at Carnegie Mellon University. His work was used in shaping national policies in forensic science, education and criminal justice.
The couple married in 1965 and had moved to Pittsburgh in the early 1980s. Joyce began her work at the centre in 1983. The couple had two sons and several grandchildren.
DANIEL STEIN
Daniel Stein was a visible member of Pittsburgh's Jewish community, where he was a leader in the New Light Congregation and his wife, Sharyn, is the membership vice-president of the area's Hadassah chapter.
"Their Judaism is very important to them, and to him," said chapter co-president Nancy Shuman. "Both of them were very passionate about the community and Israel."
Stein, 71, was president of the Men's Club at Tree of Life. He also was among a corps of the New Light members who, with Wax and Richard Gottfried, 65, made up "the religious heart" of the congregation, Cohen, the congregation co-president, said.
Stein's nephew Steven Halle told the Tribune-Review that his uncle "was always willing to help anybody."With his generous spirit and dry sense of humour, "he was somebody that everybody liked," Halle said.
RICHARD GOTTFRIED
Richard Gottfried was preparing for a new chapter in his life.
Gottfried ran a dental office with his wife and practice partner Margaret "Peg" Durachko Gottfried.
The dentist, who several have noted often did charity work seeing patients who could not otherwise afford dental care, was preparing to retire in the next few months.
He, with Wax and Stein, "led the service, they maintained the Torah, they did what needed to be done with the rabbi to make services happen," Cohen said.
