Friedrich "Fritz" Carl Heckert (28 March 1884 – 7 April 1936) was a German trade unionist and politician who co-founded the Spartacus League and the Communist Party of Germany.

[1][2] Fritz Heckert was born in Chemnitz on March 28, 1884, the son of a working-class family; his father was a knife maker and his mother a glove weaver.

After the death of Karl Wilhelm Stolle, Heckert ran in the Reichstag by-election on 13 May 1918 in the Kingdom of Saxony 18 constituency, but was easily defeated by Social Democrat Richard Meier.

At the side of his friend Brandler, Heckert rose to the Central Committee of the KPD (ZK) after the unification party congress with the USPD in December 1920.

[1] As a member of the party leadership, Heckert was appointed Minister of Economic Affairs of the Free State of Saxony after Minister-President Erich Zeigner formed an SPD-KPD coalition government on October 12, 1923.

He served in the Zeigner Cabinet for 19 days during the German October until President Friedrich Ebert issued a Reichsexekution, sending the Reichswehr to forcibly dissolve the government.

Elected to the Politburo at the 11th Party Congress in 1927, he headed the trade union department of the Central Committee until April 1928, after which the Comintern transferred him to the Profintern in Moscow.
