Born to Adolph Riccardi and Ifigenia Rasini Di Mortigliengo in Pavia, Italy, (although other sources claim Saluzzo), Riccardi entered the Italian military academy to become a successful career soldier. Seeing action with the Italian marines in the Boxer Rebellion in 1900–1901, the Far East Campaign of 1905, and the First World War, Riccardi was awarded several medals for valor. These medals included the Bronze Medal of Military Valor, China Campaign Medal (1900–1901), Gold Cross for Seniority, War Merit Cross, Medal of War (1915–1918), Unit of Italy memorial medal, inter-allied Victory Medal, among others.

Heading the Cabinet to the Ministry of Navy from 6 February until 13 May 1925, Riccardi was finally made an admiral on 8 September 1932. Following his admission into the La Spezia (PNF) political party in 1934, he won promotion to vice admiral on 27 December 1935.

Riccardi would go on to hold a series of positions including Chief Executive Officer Official of the Case of Navy and Member of the Permanent Commission for the lighting system and signalling of the coasts on 12 August, as well as General Manager of the Staff and the Military Services to the Ministry of Navy on 22 August 1935, before becoming Ministry of Marine Director General of Personnel.

Riccardi's first major engagement took place at the Battle of Taranto, when British carrier-borne torpedo bombers delivered a devastating surprise attack against Italian naval targets in the harbor of Taranto on the night of 11–12 November 1940.

Succeeding Admiral Domenico Cavagnari as chief of staff of the Italian Royal Navy (Regia Marina) on 11 December 1940, Riccardi became de facto commander of the existing Ministries for wartime aviation and naval forces. Riccardi did this in addition to his position as the Department of the Navy's Undersecretary of State.

Meeting with representatives of the Nazi Germany's Kriegsmarine, Riccardi led the Italian Royal Navy delegation, along with Raffaele de Courten, Emilio Brenta, and Carlo Giartosio during the Conference of Merano, from 13 February to 14 February 1941.

Riccardi was forced to surrender both positions on 25 July 1943, following the downfall of Italian dictator Benito Mussolini's fascist regime. Under the new Pietro Badoglio administration, Raffaele de Courten officially succeeded Riccardi as Naval Minister and, after 1945, the position came up in the new Ministry of Defense.
