Originally, the curie was a comparison of the activity of a sample to the activity of one gram of radium, which was measured at 37 billion disintegrations per second. For example, a radioactive sample undergoing 74 billion disintegrations per second has an activity of 2 curies.

Curie. ... It was originally defined as "the quantity or mass of radium emanation in equilibrium with one gram of radium (element)" but is currently defined as 1 Ci = 3.7×1010 decays per second after more accurate measurements of the activity of 226Ra (which has a specific activity of 3.66×1010 Bq/g).
Example
1910, in the meaning defined at sense 1
