Supernova theory suggests that stellar-origin black holes cannot attain masses in the range 50-135 solar masses in isolation. We argue here that this mass gap is filled in by black holes which grow by gas accretion in dense stellar clusters, like proto-globular clusters. The accretion proceeds rapidly, during the first ten Myrs of the life of the cluster, before the remnant gas is depleted. We predict that binaries of black holes within the mass gap can be observed by LIGO.
