[3] He was further educated at the Ohio State University in Columbus and the Massachusetts Institute of Technology in Boston, graduating from the latter in 1887.

After two years working for Babb, Cook & Willard in New York City, he returned to Columbus c. 1889 and opened his own office.

[6] In 1922 Harding, as President, appointed Packard architect of the United States pavilion at the Independence Centenary International Exposition in Rio de Janeiro in Brazil.

[5] Located on what is now Avenida Presidente Wilson, this original building was replaced by a new embassy, now the consulate, in 1952.

In his private practice, Packard was associated with several other professionals, including architect Ralph Snyder, engineer Edward F. Babbitt and superintendent Lorenzo D. Mathews.

Many buildings designed by Packard, independently and with Yost, have been listed on the United States National Register of Historic Places.
