2097: Spaced

In each of 14 clues, the cryptic indication omits reference to one letter of the answer.  These letters must be highlighted, to reveal the name of someone who has had a number of 43, some of which are unclued lights, individually or paired.  Each of the remaining clues comprises a definition part and a hidden consecutive jumble of the answer including one extra letter; the extras are the unchecked letters of all seven unclued lights. One unclued light consists of three words, and one consists of two words.
