Nominations for The Post's second annual Liberty Medal Awards are pouring in, with New Yorkers looking to honor the unsung heroes of the city.

Today, we introduce a few of the nominees who have already made New York a better place through their selfless actions and unflagging dedication.

In 1978, Town Hall was a battered concert hall on West 43rd Street that had seen better days. Its owner, New York University, was going to sell the theater, and the wrecking ball was its likely future.

But then, businessman Marvin Leffler and a group of NYU alumni stepped in, bought the building from the university for $10 and saved the concert hall.

That was 25 years ago, and since then, Leffler and the Town Hall Foundation have restored the hall to its place as a renowned venue that showcases important dance, music and literary performances.

As the unpaid president of the foundation, Leffler has kept Town Hall in the black.

"Marvin Leffler has a hand in everything, from fund-raising to steering the direction that Town Hall goes in," said Kerrie Smith, the publicity director of Town Hall, who's nominated Leffler for the New York Post's Community Liberty Medal.

"In 1978, when we took possession of Town Hall, we had a theater where everything had to be redone," Leffler, 78, told The Post.

Leffler was working in manufacturing when the new board took over Town Hall, and he mounted a massive fund-raising campaign to restore the theater to its 1921 splendor.

"We acted like insurance agents, hitting up our friends and family for money," he said. Next, he coordinated the $1.5 million renovation, which was completed in 1983.

"We did it through tight fiscal management," he said. "We did it on time and did not go a penny over budget."

Nowadays Town Hall runs an eclectic schedule of events. Rocker Lou Reed will play there this month, satirist David Sedaris sells out the house and the "Broadway by the Year" series has been a popular audience hit. Town Hall has also received kudos and awards for its recent Black History Month program.

Since he retired 10 years ago, Leffler puts in 40-hour weeks at Town Hall and still oversees fund-raising and renovations.

"We have never operated at a loss," Leffler said proudly, "and we now have a $500,000 endowment."

And when he looks back at his achievements, it's with a sense of wonder about how he did it all.

"There was a touch of ignorance there," he said.

"I didn't know what couldn't be done."
