Morris Morisovich Konradi, also known as Moritz Moritzovich, was born on May 29, 1896, in St. Petersburg to a family of Swiss immigrants in Russia. His father bore the same name, and his uncle Viktor-Edward Mavrikievich Konradi owned confectionery factories in St. Petersburg and Moscow. Morris graduated from gymnasium and the Pavlov Military School.

He studied at the St. Petersburg Polytechnic Institute but left for the front in 1914, after his second year, with permission from Emperor Nicholas II, as he was a Swiss citizen. As a lieutenant, Konradi was wounded and awarded the Order of St. George IV class.

In January 1916, he graduated from officer school in Petrograd and fought on the Romanian front. From there, he embarked on a campaign from Yash to the Don as part of the Drozdovsky detachment.

During the Red Terror, Konradi lost his father, who died after being beaten by the Cheka, and his uncle, who was shot by the Bolsheviks as a hostage. One of his brothers also perished, and his aunt was killed by robbers.

On May 10, 1923, in Lausanne, at the restaurant of the "Cecil" hotel, Morris Konradi shot Soviet diplomat Vaclav Vorovsky. Afterward, he handed the weapon to the maître d'hôtel and surrendered to the police, stating: "I did a good deed; Russian Bolsheviks have ruined all of Europe... This will benefit the whole world."

At the trial, Konradi declared: "I believe that the destruction of every Bolshevik contributes to the progress of humanity. I hope that other brave souls will follow my example, demonstrating the greatness of their feelings!"
