Papers from the Lost Culture of Array Languages

2012 is the 50th anniversary of Ken Iverson's A Programming Language , which described the notation that became APL (even though a machine executable version of APL didn't exist yet). Since then there's been APL2, Nial, A+, K, Q, and other array-oriented languages. Iverson (1920-2004) teamed with Roger Hui to create a modern successor to APL, tersely named J, in the late 1980s.
