Here is a short list of famous people who share Keith's date of death.
P.T. Barnum - Circus Organizer and hoaxer. Died in 1891 at age 80. The saying "A sucker born every minute" is often attributed to him. May have been uttered by a contemporary.
Henry Ford - Automotive Pioneer. Died in 1947 at age 83. Streamlined auto industry.
Johnny Hart - Cartoonist. Died in 2007 at age 80. Created the comics strips B.C. and Wizard of Id. Stirred up controversy with his highly evangelical Easter Sunday panels in B.C.
Speaking of Easter, I found one reference on the Internet that Jesus Christ died on April 7th.
If that is indeed historically accurate, I find it very encouraging that Keith died on the same day that His savior died for His sins and those of the world. Because of Christ's death and subsequent Resurrection, I will one day see Keith again in Heaven.
