mass gainer donor observational li\`egeZusammenfassung
Many massive binary systems undergo mass and angular momentum transfer over the course of their evolution.
This kind of interaction is expected to deeply affect the properties of the mass donor and mass gainer and to leave various observational signatures.
The most common smoking guns of a past mass transfer episode are notably rapid rotation of the mass gainer and altered surface chemical abundances of the stripped mass donor star.
Quantitative observational studies of evolved massive binaries are crucial to gain insight into poorly constrained parameters of binary evolution models such as the fraction of mass lost by the mass donor that is actually accreted by the mass gainer.
Yet, drawing conclusions about a past mass transfer episode requires a detailed analysis of all aspects of a binary system which sometimes leads to unexpected results.
In this contribution, we review the existing observational evidence for past mass exchange events in massive main-sequence and post main-sequence binaries.
