Biotech Power Couple to Split

Local power couple Sachiko Kuno and Ryuji Ueno, cofounders of Bethesda-based Sucampo Pharmaceuticals and the S&R Foundation — which owns three high-profile Georgetown properties: Evermay estate and Halcyon House, purchased in 2011, and the former Fillmore School, purchased in 2015 — are divorcing. They have lived apart since September 2014. The divorce is uncontested, according to papers filed in Montgomery County, where they had lived.
