findagrave states he was born several weeks after his brother Harry. Since Harry died only a few weeks of age, my assumption is the July 1910 birth date on his grave is correct, and that Robert was born perhaps a year after.

Executive of Drug Firm In Wichita Dies at 56
Robert B. Dockum, 56, of 40 Stratford, Eastborough, past president of Dockum Drugs and founder of Rexall Drug Co. Association, died Sunday.
A lifetime resident of Wichita, he graduated from Wichita High School and the Uniyersity of Kansas School of Pharmacy.
He began his career with Dockum Drugs as assistant manager of Dockum Drug Store No. 7. His father, Harry, had founded the Dockum Drug chain in 1900 with a store at 128 N. Main.
When his father died in 1941, Dockum became president of the chain and pioneered a new concept in drug stores with the opening of a drug store-supermarket complex at Douglas and Oliver in 1942.
Adams Drug Co., Pawtucket, R.I., bought the chain from Robert Dockum in 1961, when he retired. The Dockum drug store empire, which once owned 10 stores in the Wichita area, has been reduced to three stores.
Dockum was past president of the International Rexall Club and a director of the Rexall Drug Co. He had been on the board of advisers of Rexall Drug Co., past president of the Association of Rexall Clubs, and past vice president of the Southern Drugstore Association.
In 1954, he founded the Rexall Drug Co. Association and was president of the group. He was also a member of the Chamber of Commerce, Rotary Club, Wichita Country Club, St. James Episcopal Church, and a director of the First National Bank and Boulevard State Bank.
Survivors include two daughters, Mrs. Burton Schmidt, Wichita, and Mrs. John Trombold, La Jolla, Calif., and a sister, Mrs. Ruth Dockum Boggs, Houston, Tex.
Byrd-Snodgrass Funeral Home has charge.
