The Standard Alphabet by Lepsius is an alphabet developed by Karl Richard Lepsius to write African languages. Published 1855 and in a revised edition (with many more languages added) in 1863. It was comprehensive but it wasn't used much as it contains a lot of diacritic marks and therefore was difficult to read, write and typeset at that time.
