Who was the only general/admiral to turn down 5 stars?

Following the establishment of the General of the Army grade on December 14, 1944, Army Regulations 600-35 were changed to prescribe that Generals of the Army would wear five stars. John J. Pershing General Pershing continued to wear only four,but he remained preeminent among all Army personnel, by virtue of Congressional action and Army Regulations governing rank and precedence, until his death on July 15, 1948.

he chose to only wear 4 not 5 so to me that means he turned it down.

And why he would do that is beyond me! Service in the military for more than 30 years rakes in a hefty 75% retirement (compared to the 50% of base pay the rest of us get).

Which would you rather have?

75% of a 4-star salary
75% of a 5-star salary

(For the love of Pete! He had already put in the time! All he had to do was say "yes"!)
