We consider matrices $M$ with entries $m_{ij} = m (\lambda_i, \lambda_j)$ where $\lambda_1, \ldots, \lambda_n$ are positive numbers and $m$ is a binary mean dominated by the geometric mean, and matrices $W$ with entries $w_{ij} = 1/m (\lambda_i, \lambda_j)$ where $m$ is a binary mean that dominates the geometric mean. We show that these matrices are infinitely divisible for several much-studied classes of means.
