<prompt> Qedela lo musho olandelayo: U-Alva C. Ellisor wazalwa ngo-April 26, 1892 eGalveston, eTexas. Lapho eneminyaka eyisishiyagalombili ubudala, wasinda  <response>: Isiphepho Esikhulu SaseGalveston sango-1900. Wayenabafowabo ababili abancane ababulawa kuleso senzakalo. Ukuba yi-valedictorian yekilasi lakhe, kamuva, ngo-1915, waphothula iziqu njengomfundi ohlonishwayo kuGeology eNyuvesi yaseTexas, futhi wayengomunye wabesifazane ababili abaphothula emkhakheni wakhe. Ngemva kokuthweswa iziqu, u-Elisor wabamba isikhundla sokufundisa eBall High School. Lokhu kwaba okwesikhashana njengoba wanquma ukubuyela eyunivesithi futhi afunde ngethemba lokuba uprofesa. Ngesikhathi esifanayo lapho u-Elisor efunda, wayephinde enze ucwaningo emkhakheni we-geology ngaphansi kokuqondisa kwabafundisi bakhe, uProfesa Francis L. Whitney noProfesa Hal P. Bybee. Elinye lamaphepha akhe okuqala ocwaningo lanyatheliswa ngokushesha ngemva kwalokho, ngo-1918, elalinemivubukulo eminingi yemivubukulo yakhe. Lezi zinsalela ezifanayo zafakwa encwadini ethi Handbook of Texas Cretaceous Fossils, kaW.S. Adkin 1928. Ngawo lowo nyaka, u-Elisor waqala ukusebenza njengoprofesa e-University of Kansas efundisa i-geology futhi ngo-1919 wakwazi ukusebenzisa ulwazi lwakhe ngenkathi esebenzela i-Kansas Geological Survey.
