So far, Fischer has given 319 pints of blood and he will do it again Tuesday in Woodbury, bringing his lifetime donation to a total of 40 gallons.

Only one other person in the United States has given more blood, according to a New York Blood Center official – Maurice Wood, 83, a retired federal railroad inspector from St. Louis. Fischer, who last spoke to Wood a few months ago, said he and Wood are engaged in a friendly rivalry.

“He’s about six or seven pints ahead of me,” said Fischer.

“He’s a one-man army, who has helped almost a thousand people,” said Schaffler, who met Fischer more than two decades ago at a blood drive in Manhattan. (via Massapequa blood donor closes in on 40 gallons)
