Johannes Loersfeld

Johannes Loersfeld (fl. 1525–1528) was a German printer at Erfurt in the Archbishopric of Mayence.

Among his significant editions was the Erfurt Enchiridion, an early Lutheran hymn-book. Loersfeld's edition of 1524 appeared at much the same time as that of his rival Matthes Maler but was probably the first of this work.[1][2]

gollark: No. Someone with more physics knowledge could answer better than me, but, very approximately: "laser" stands for "light amplification by stimulated emission of radiation", and describes a specific way to generate light through some magic process using a "gain medium" and optical feedback thing.
gollark: That would not actually be a laser.
gollark: I think you would need a hilariously expensive and large free electron laser for that.
gollark: Lasers are "bright" because the output light is "compacted" into a small area.
gollark: *Fairly* sure, yes.
