Quote from The Kansian site article;
Steuben glass is among the world’s preeminent and decorative arts, and the Wichita Art Museum has the second-largest museum collection of Steuben in the country.

Steuben glass has been produced in Corning , N.Y. , since 1903, and is one of America ’s finest luxury art products. The museum’s collection is largely due to the generosity of the late Dr. F. Price Cossman, who left his personal collection of Steuben to the museum. Cossman also established a trust to help the museum expand his core collection. The Wichita Art Museum ’s Steuben glass collection has grown to include more than 100 example.

He certainly must have been since the majority of their collection is credited to him. I did a Google search and there are plenty of Crossman’s in Wichita area and in Kansas. He was a Doctor for 51 years and died in 98 and had a tax free Memorial Trust in Kansas. No mention of his association with the museum or as a collector of Steuben.
The assets of the trust in 2008 were $4,237,621.00
Stephen Gleissner, the Curator at the Wichita Museum provides this detail.

Thank you for your interest. F. Price Cossman was a local physician whose favorite hobby was travel, during the course of which he acquired a special interest in Steuben glass. He never married and had no direct heirs. Upon his death, his Will stipulated that his collection of 39 works of Steuben be given to the Wichita Art Museum , along with a trust fund to add to his collection and develop a Steuben collection of significance. No one knows what he may have thought of Frederick Carder.

He had two Carder-era vases in his collection; the other 37 were contemporary pieces that he
purchased from Steuben boutiques. His sister told me that he always loved colored glass, and when they were children both were entranced by the brightly-colored stained glass windows in the family’s Victorian farm house. She told me he would have been thrilled with the colored glass we have acquired. I suspect he purchased clear Steuben because he encountered it in the department stores he frequented. Since he was not an “antiques” collector, and since the Steuben retail shops used not to carry Carder-era glass, he probably just wasn’t very familiar with colored Steuben, though obviously he was to some degree since he owned two colored vases. There is no indication of where he found them or how he came to acquire them.
Perhaps he perceived the clear glass as more fitting to his modern town house.
For Carder eye candy see.
