Gregg shorthand, is, like cursive longhand, completely…
1888 CE
Invented by John Robert Gregg in 1888, Gregg shorthand will become the most popular form of pen stenography in the United States; its Spanish adaptation will become fairly popular in Latin America, and the system is still in use today.
There is a reasonable possibility that John Robert Gregg structured his shorthand on the Mnemonic major system based on the previous work of Pierre Hérigone and others following the publication of The Anti-Absurd or Phrenotypic English Pronouncing and Orthographical Dictionary by Major Beniowski in 1845.
Gregg will say he initially set out to improve the English adaptation by John Matthew Sloan of the French Prévost Duployé Shorthand, while working with one of Sloan's sales agents, Thomas Malone.
Malone had published a system called Script Phonography, of which Gregg had asserted a share in authorship was owed to him.
Angered by Malone, Gregg resigns from working with him and, encouraged by his older brother Samuel, publishes and copyrights his own system of shorthand in 1888.
It is put forth in a brochure entitled Light-Line Phonography: The Phonetic Handwriting, which he publishes in Liverpool, England.
