I just want to acknowledge the contributions of two teams to the discovery of gravitational waves. These groups are only part of the wider community and I highlight them for purely personal reasons.

The Polish group

The Virgo-POLGRAW group,  lead by   Prof. Andrzej Królak at IMPAN.

The Welsh group

The Cardiff Gravitational Physics Group,  and within that the Data Innovation Institute lead by Prof Bernard F Schutz.
