Rather amazingly, every one of them was coined by Sir Thomas Browne, who was born on this day in 1605 and died, with exemplary symmetry, on the same day in 1682. Browne has, indeed, a total of 775 entries in the OED for first use of a word - not all of them as useful, or as lasting, as those above. Even if he had not written his great works - Hydriotaphia (Urn Burial), Religio Medici and the vast and strange Pseudodoxia Epidemica (Vulgar Errors) - he would have earned some fame in the world of words.
Sir Thomas was also, very probably, the first man to say 'I am the happiest man alive.' And, from what we know of his life and character and can adduce from his portrait, it seems likely to have been true.
