A longtime fighter of crime in New York City, Charles Kleinberg passed away on May 22 as a result of COVID-19.

He was born on Dec. 8, 1948 in Brooklyn, N.Y., to Sam and Doris Kleinberg.

Despite earning degrees in mathematics—a bachelor’s degree at Brooklyn College and master’s degree at Yale University—he went on to obtain a J.D. at New York University School of Law, graduating first in his class in 1976.

He found his calling in fighting for justice, serving as a federal prosecutor in the Eastern District of New York for 38 years.

Known for presenting evidence logically along the lines of his academic studies, Kleinberg tried more than 70 cases and 70 appeals. He gained a reputation for taking down the corrupt and morally bankrupt in his carefully detailed manner.

Kleinberg never stopped studying, earning a doctorate in philosophy from Columbia University in 1994 while serving in his role as a federal prosecutor. After retiring in 2018, he re-enrolled in his alma mater, Brooklyn College, to pursue physics.

He is survived by his wife, Judith Adams Eschweiler; daughter Wendy April Kleinberg; and sisters Sharon Kleinberg and Debbie Bancroft Kleinberg.
