His father had a lumber manufacturing business in Pequaming, Michigan named Charles Hebard and Sons, where he had co-developed a saw-mill and associated company town. Later, his father established the Hebard Cypress Company, which constructed the Waycross and Southern Railroad specifically to harvest the cypress trees in the Okefenokee Swamp.^[2] The family also had houses in Thomasville, Georgia and Chestnut Hill, Philadelphia, Pennsylvania. Hebard attended Asheville School in North Carolina, educated by a private tutor, before graduating from Yale University in 1910.^[3][4] At Yale, Hebard won prizes as a member of the gun team.^[4][5] At the time of his graduation, he intended to enter the lumber business.^[4]

He worked for brokers and bankers, Henry & West from 1910 to 1912 in Philadelphia. From 1910 to 1928, he was a research associate at the Academy of Natural Sciences of Philadelphia. For ten years after that he was the curate of entomology. Between 1938 and 1940, he was a research fellow. In 1945 and 1946, he was a benefactor of the academy. During field trips to Western Europe, Panama, Cuba, Jamaica, Columbia and the Bahamas, Hebard built a collection of 250,000 specimens, which he presented to the academy in 1945. He wrote 197 journal articles and monographs on entomological topics, either individually or jointly with his fellow entomologist, James A. G. Rehn, comprising over 5,000 pages.^[6] He described over 800 new species of orthopteroids; this included 44 new species and ten new genera of Phasmids (six new genera on his own and four as co-author with Rehn).^[5] Forty orthopteroid species and nine genera have been named after him, including: one Phasmid species, Ilocano hebardi Rehn & Rehn, 1938; three species of Mantids, and two genera: Hebardia Werner, 1921 and Hebardiella Werner, 1924; eight species of Cockroaches, and four genera: Hebardina Bei-Bienko, 1938, Hebardula Uvarov, 1939, Euhebardula Princis, 1953 (a replacement name for Hebardula Princis, 1950); and 28 species of Orthoptera, three genera: Hebardiniella Chopard, 1932, (emendation of Hebardinella Chopard, 1932), Hebarditettix Günther, 1938^[7] and Hebardacris Rehn, 1952.^[5] He was a member of American Entomological Society, and for a time it's Treasurer, and was elected a Fellow of the Entomological Society of America.^[8][1] He was an honorary member of the Entomological Society of France, and also of the Columbian Natural Science Society.^[1]
