Final answer:
Aaron S. Williams and Carrie Hessler-Radelet served as Peace Corps Directors during President Obama's administration, with Williams being the director from 2009 to 2012 and Hessler-Radelet taking over in 2012, confirmed in 2014.
Step-by-step explanation:
The name of the Peace Corps Director appointed by President Obama is not explicitly mentioned in the provided resources. However, historically, the creation of the Peace Corps was a significant program of the Kennedy administration and its first director was Sargent Shriver, a relative of President Kennedy.
For the term during President Obama's presidency, Aaron S. Williams served as the Director of the Peace Corps from 2009 to 2012, followed by Carrie Hessler-Radelet, initially as acting director since 2012 and then confirmed in 2014.
While the FCC commissioners and various other appointments are mentioned, such as Roberta Achtenberg to the United States Commission on Civil Rights, Elizabeth Warren's connection with the Consumer Financial Protection Bureau (CFPB), and Richard Cordray's appointment as the director of CFPB are noted, they are not related to the Peace Corps directorship.
