Album 15 consists of photographs predominantly taken between 1964 and 1969. It is unclear who put the album together, but the content's focus primarily on Henri Nouwen and his professional life as a priest. Approximately half of the album's pages are dedicated to Nouwen's departure for and stay at the Menninger Clinic in Topeka, Kansas. The photos, many of which were professionally taken by an unknown photographer, show Nouwen having a meal and posing for photos with Laurent J.M., Maria, Paul, Laurent and Laurien Nouwen, before leaving for the United States; Nouwen with family and friends, including Toon Colen, at the Schiphol airport in Amsterdam; portraits of Nouwen speaking while seated; Nouwen participating in a talk with Menninger colleagues, including Thomas W. Klink, during a visit from Cardinal Alfrink; and scenic shots of Topeka including the Most Pure Heart of Mary church. Other photos in the albums are dedicated to a trip to Chicago, Illinois and Niagara Falls; unidentified church services; a party at the Dijnselburg Huis Ter Heide, in Utrecht, in celebration of Nouwen's 12 1/2 year anniversary of his ordination as a priest; Don McNeill's [graduation?] from [Notre Dame University?]; portraits of family and friends; a trip to an unidentified location. Of interest is a photo, tucked into the front cover of the album, of Nouwen participating in a church service in St. Peter’s Basilica during Vatican II and the inclusion of the photo and dinner menu from his ordination as a priest, in 1957, as a marker of time placed along with the 12 1/2 year anniversary photos and invites.
