Geraldine Ferraro, shown during the 1984 U.S. presidential elections, when she was Walter Mondale's running-mate, has died in Boston.

Geraldine Ferraro, the first woman to run for U.S. vice-president on a major party's ticket, has died, a family spokesman said Saturday. She was 75.

Ferraro, who has had blood cancer since 1998, died in hospital in Boston.

The former Democratic congresswoman from New York City was best-known for being Walter Mondale’s choice as running-mate in the 1984 presidential election.

That year, the Democrats suffered a disastrous loss — to Ronald Reagan, the incumbent Republican president, and George Bush, his vice-president. Mondale and Ferraro won only in Minnesota, Mondale’s home state.

Ferraro later ran twice unsuccessfully for the Democratic nomination for U.S. Senate in New York.
