Ed Summers
As well as chatting on irc and the mailing lists (mostly helping out with MARC encoding problems) Ed has done a huge amount of work on modules for dealing with MARC records in perl. Including MARC::Record, MARC::XML and MARC::Charset which Koha uses. Without these modules building MARC support into Koha would have been much much harder. So thanks Ed and also thanks CPAN 🙂
