Problem: Background: Ellington was born on April 29, 1899, to James Edward Ellington and Daisy (Kennedy) Ellington in Washington, D.C. Both his parents were pianists. Daisy primarily played parlor songs and James preferred operatic arias.
Context: From 1936, Ellington began to make recordings with smaller groups (sextets, octets, and nonets) drawn from his then-15-man orchestra and he composed pieces intended to feature a specific instrumentalist, as with "Jeep's Blues" for Johnny Hodges, "Yearning for Love" for Lawrence Brown, "Trumpet in Spades" for Rex Stewart, "Echoes of Harlem" for Cootie Williams and "Clarinet Lament" for Barney Bigard. In 1937, Ellington returned to the Cotton Club which had relocated to the mid-town Theater District. In the summer of that year, his father died, and due to many expenses, Ellington's finances were tight, although his situation improved the following year.  After leaving agent Irving Mills, he signed on with the William Morris Agency. Mills though continued to record Ellington. After only a year, his Master and Variety labels, the small groups had recorded for the latter, collapsed in late 1937, Mills placed Ellington back on Brunswick and those small group units on Vocalion through to 1940. Well known sides continued to be recorded, "Caravan" in 1937, and "I Let a Song Go Out of My Heart" the following year.  Billy Strayhorn, originally hired as a lyricist, began his association with Ellington in 1939. Nicknamed "Swee' Pea" for his mild manner, Strayhorn soon became a vital member of the Ellington organization. Ellington showed great fondness for Strayhorn and never failed to speak glowingly of the man and their collaborative working relationship, "my right arm, my left arm, all the eyes in the back of my head, my brain waves in his head, and his in mine". Strayhorn, with his training in classical music, not only contributed his original lyrics and music, but also arranged and polished many of Ellington's works, becoming a second Ellington or "Duke's doppelganger". It was not uncommon for Strayhorn to fill in for Duke, whether in conducting or rehearsing the band, playing the piano, on stage, and in the recording studio. The 1930s ended with a very successful European tour just as World War II loomed in Europe.
Question: did they produce any music?
Answer: Well known sides continued to be recorded, "Caravan" in 1937, and "I Let a Song Go Out of My Heart" the following year.

Background: Lillian Evelyn Moller Gilbreth (May 24, 1878 - January 2, 1972) was an American psychologist, industrial engineer, consultant, and educator who was an early pioneer in applying psychology to time-and-motion studies. She was described in the 1940s as "a genius in the art of living." Gilbreth, one of the first female engineers to earn a Ph.D., is considered to be the first industrial/organizational psychologist.
Context: For more than forty years, Gilbreth's career combined psychology with the study of scientific management and engineering. She also included her perspectives as a wife and mother in her research, writing, and consulting work. Gilbreth became a pioneer in what is now known as Industrial and organizational psychology. She helped industrial engineers recognized the importance of the psychological dimensions of work. In addition, she became the first American engineer ever to create a synthesis of psychology and scientific management. (Gilbreth introduced the concept of using psychology to study management at the Dartmouth College Conference on Scientific Management in 1911.)  In addition to jointly running Gilbreth Incorporated, their business and engineering consulting firm, Lillian and Frank wrote numerous publications as sole authors, as well as co-authoring multiple books and more than fifty papers on a variety of scientific topics. However, in their joint publications Lillian was not always named as a co-author, possibly due to publishers' concerns about a female writer. Althhough her credentials included a doctorate in psychology, she is less frequently credited in their joing publications than her husband, who did not attend college.  The Gilbreths were certain that the revolutionary ideas of Frederick Winslow Taylor would be neither easy to implement nor sufficient; their implementation would require hard work by engineers and psychologists to make them successful. The Gilbreths also believed that scientific management as formulated by Taylor fell short when it came to managing the human element on the shop floor. The Gilbreths helped formulate a constructive critique of Taylorism; this critique had the support of other successful managers.
Question: Did she have any other career highlights?
Answer:
she became the first American engineer ever to create a synthesis of psychology and scientific management.
