Early life and education 
Academic career 
Reiner joined the Chicago faculty in 1956. Extensive documentation and planning for the Chicago Assyrian Dictionary had been underway at the university since 1921. Reiner, along with A. Leo Oppenheim, led the team after World War II to publish the first of what would be 21 volumes in 1956. She took over the project at Oppenheim's death in 1974; in total, she worked on the project for 44 years. Twenty volumes were released over 55 years.
Reiner was the John A. Wilson Distinguished Service Professor Emerita in the University's Oriental Institute, and the longtime Editor of the Chicago Assyrian Dictionary (1974-1996). Among other accomplishments, Reiner was one of the few people in the world proficient in the Elamite language.
She wrote numerous books and articles. Upon her retirement in 1996, she continued to contribute to the Dictionary.
