In the Chapel of the Massachusetts Institute of Technology, Cambridge, Mass., Martha Stark Draper, regional director for the Southeast Alumni Association for MIT, and Steven Roland Ditmeyer, associate administrator of the Federal Railroad Administration in this city, were married on May 26. The Rev. Jeffrey Cave performed the double ring ceremony uniting the daughter of Dr. and Mrs. Charles Stark Draper of Newton, Mass. to the son of Mr. and Mrs. Roland Ditmeyer of St. Louis, Mo. The garden reception followed at the home of her parents.

The bride, given in marriage by her father, wore a white chapel length chiffon gown with a Victorian neckline and full bishop sleeves of chiffon appliqued with satin venise lace and she carried a bouquet of phaelanopsis, lily of the valley and ivy. Wearing yellow linen in the empire style and holding white daisies, yellow roses and cornflowers was the honor attendant, Mrs. James Stark Draper. Allison Stark Draper was her aunt's flower girl; she wore white eyelet and carried spring flowers. Stark Christiaan Draper, the bride's nephew, was ring bearer. John E. Harman of Maryland and Alexandria, Va., was best man with James Stark Draper and John Clayton Draper, brothers of the bride, as ushers.

The newlyweds honeymooned on Nantucket Island and will make their home in Washington, D.C., after Mr. Ditmeyer's temporary assignment as acting general manager of the Alaska Railroad in Anchorage. CAPTION: Picture, no caption, Bachrach
