Born in Topeka, Kansas in mid-January 1892 and was a Topeka High School graduate. In 1911 he entered the United States Military Academy, at West Point, New York. He graduated four years later as a second lieutenant in the Infantry Branch of the United States Army as part of the West Point class of 1915, also known as "the class the stars fell on". Among those he graduated with were Dwight D. Eisenhower, Omar Bradley, James Van Fleet, Joseph T. McNarney and many others who, like Ryder, would also attain general officer rank. Ryder's first assignment was with the 30th Infantry Regiment and, later, was on border duty near Fort Sam Houston, Texas. He then served with the Reserve Officers Training Corps in New York and, by the time of the American entry into World War I he was a company commander in the 16th Infantry Regiment. Ryder, together with the rest of his regiment, which was now part of the 1st Infantry Brigade of the newly created 1st Infantry Division, was sent to the Western Front and arrived there in June 1917, one of the first units of the American Expeditionary Force to be sent overseas in World War I. Promoted to captain, commanding Company 'B' of the 1st Battalion, 16th Infantry, Ryder and his regiment, not immediately engaged in combat, spent almost a year being trained in trench warfare tactics from the French Army. He was promoted to major on June 17, 1918 and assumed command of the 1st Battalion, 16th Infantry Regiment. A month later, he led the battalion in the Battle of Soissons, suffering heavy casualties, including Ryder himself, who was wounded by German artillery but continued to lead his men. Of the 1,100 men of Ryder's battalion who went "over the top" on July 18, 1918, there were less than 50 remaining five days later. However, Ryder, in his first battle, had performed well and was awarded the Distinguished Service Cross, the nation's second highest award for valor in the face of the enemy, the Silver Citation Star and the Purple Heart. Wounded in the heart, he spent the next few weeks recovering in the hospital and soon returned to the command of his battalion. He again led the battalion in the Meuse-Argonne Offensive in early October 1918, where it captured Hill 272, a dominant terrain feature in the 1st Division's sector which had brought the division to a standstill for three days. After personally observing his battalion's objective, he gave verbal orders to his company commanders and outlined his plan of attack. On October 8 the division artillery concentrated fire on the hill and Ryder's battalion, with Ryder, as at Soissons, again leading from the front, attacked the hill at 8:30am the next day, under cover of a thick fog and supported by machine guns and a huge artillery barrage. Working in small units to outflank the enemy machine guns and mortars, capturing or destroying enemy positions, the battalion had, by 11:00am, secured all its objectives and captured more than 50 machine guns and began to consolidate its position. For his personal leadership in the battle Ryder was awarded with a second Distinguished Service Cross, two of twenty five to be awarded to men of the 1st Division. World War I came to an end just over a month later with the signing of the Armistice with Germany coming into effect on November 11, 1918 at 11:00am. Ryder's war was over and the personal lessons he learned would remain with him and serve him well in the future.
After the end of the conflict Ryder remained in the army, served on occupation duties in France and Germany. Ryder had been decorated with two Distinguished Service Crosses, a Silver Star and a Purple Heart for his service in the war. Between the wars, Ryder served in various posts, including the Command and General Staff School, Fort Leavenworth, Kansas; the 15th Infantry in Tientsin, China; Assistant Instructor of Tactics, Commanding Company of Cadets at West Point and as Commandant of Cadets at West Point.
From September 2, 1944 to December 6, 1948, Ryder served as commanding general of the IX Corps, preparing for the invasion of Japan. After the Japanese surrender, he continued to serve as commanding general of the IX Corps during the occupation of Japan. Ryder retired from the Army in 1950 and died on August 17, 1960, at the age of 68.
