Problem: Extract the answer to the question from the following context. Question: When did orthography come into creation? Context: Modern Estonian orthography is based on the Newer Orthography created by Eduard Ahrens in the second half of the 19th century based on Finnish orthography. The Older Orthography it replaced was created in the 17th century by Bengt Gottfried Forselius and Johann Hornung based on standard German orthography. Earlier writing in Estonian had by and large used an ad hoc orthography based on Latin and Middle Low German orthography. Some influences of the standard German orthography for example, writing 'W'/'w' instead of 'V'/'v' persisted well into the 1930s.

Problem: Extract the answer to the question from the following context. Question: __ spawned the hit Summertime. Context: As many as five bands were on tour during the 1920s. The Jenkins Orphanage Band played in the inaugural parades of Presidents Theodore Roosevelt and William Taft and toured the USA and Europe. The band also played on Broadway for the play "Porgy" by DuBose and Dorothy Heyward, a stage version of their novel of the same title. The story was based in Charleston and featured the Gullah community. The Heywards insisted on hiring the real Jenkins Orphanage Band to portray themselves on stage. Only a few years later, DuBose Heyward collaborated with George and Ira Gershwin to turn his novel into the now famous opera, Porgy and Bess (so named so as to distinguish it from the play). George Gershwin and Heyward spent the summer of 1934 at Folly Beach outside of Charleston writing this "folk opera", as Gershwin called it. Porgy and Bess is considered the Great American Opera[citation needed] and is widely performed.

A:
Porgy and Bess
