SSTables have had a very significant impact on how many other databases have been developed. LevelDB was their first public appearance (I believe).

It's also nice to recognize the work of people who have had a significant impact on the industry. Jeff Dean & Sanjay Ghemawat are an incredible force.

They were described in the Bigtable paper, and were widely used before leveldb was published (Cassandra, for example, used sstables and LSM concerts well before 2012)
