Samuel Johnson born (18/9/1705)

https://en.wikipedia.org/wiki/Samuel_Johnson
"...made lasting contributions as a poet, playwright, essayist, moralist, literary critic, sermonist, biographer, editor, and lexicographer. The Oxford Dictionary of National Biography calls him 'arguably the most distinguished man of letters in English history'."
But it's the lexicography that we're here to celebrate. The first really comprehensive dictionary of English (in two volumes, 1755), product of about ten years' work, with a small team of assistants.
It's the definitions that Crystal most admires. He put together an anthology of them for Penguin Classics for the 250th anniversary. I haven't seen this; I have an earlier "selection" by McAdam & Milne (1982). By now there's quite a bit of it accessible online:

He gives few etymologies and very little information on pronunciation -- perhaps for the same reason Henry Sweet a century later thought it was hopeless to try to give pronunciations in the OED.
It is often said that English spelling has changed very little since Johnson's time. But he was not an innovator in this area:
"Johnson was not at all interested in reform but rather chose what he regarded as the most common spellings.
He was also concerned that homographs — different words that are spelled the same, eg bow (the weapon, etc) and bow (to bend the upper body) — could lead to misunderstandings. He therefore chose alternative spellings to reflect differences in meaning, such as stile (steps over a barrier) and style (of art, writing, etc). Before compiling the Dictionary, he himself had written '…the rules of stile, like those of law, arise from precedents…' (Plan of a Dictionary, 1747). However, one effect of all this was to make learning to spell English words even more difficult."

One example of a bad choice by Johnson which has been discussed here (or on a.u.e.) is the very peculiar spelling of "ache". It seems to have been influenced by his belief that the word was of Greek origin. Recently I have come across a couple of other examples of how Johnson's etymological misapprehensions influenced his spellings for the worse.
Can't find them right now.
Crystal's pick for a Johnsonian definition to exemplify "brevity, fulness and perspicuity":
Sorry
Grieved for something past. It is generally used of slight or casual miscarriages or vexations, but sometimes of greater things. It does not imply any long continuance of grief.
